  Issue numbers (#) refer to github issues.
  The list below consist mostly of notes of things to do before they are requested/discussed by users (at that point it usually happens on the github)
 
- - window: autofit feedback loop when user relies on any dynamic layout (window width multiplier, column). maybe just clearly drop manual autofit?
- - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list.
+ - window: maximum window size settings (per-axis). for large popups in particular user may not want the popup to fill all space.
+ - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
+ - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column). clarify.
  - window: allow resizing of child windows (possibly given min/max for each axis?)
  - window: background options for child windows, border option (disable rounding)
+ - window: add a way to clear an existing window instead of appending (e.g. for tooltip override using a consistent api rather than the deferred tooltip)
  - window: resizing from any sides? + mouse cursor directives for app.
+!- window: begin with *p_opened == false should return false.
  - window: get size/pos helpers given names (see discussion in #249)
  - window: a collapsed window can be stuck behind the main menu bar?
+ - window: detect extra End() call that pop the "Debug" window out and assert at call site instead of later.
 !- scrolling: allow immediately effective change of scroll if we haven't appended items yet
+ - splitter: formalize the splitter idiom into an official api (we want to handle n-way split)
  - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc.
  - widgets: clean up widgets internal toward exposing everything.
  - widgets: add disabled and read-only modes (#211)

  - input number: use mouse wheel to step up/down

  - text: proper alignment options
+ - image/image button: misalignment on padded/bordered button?
+ - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
  - layout: horizontal layout helper (#97)
  - layout: more generic alignment state (left/right/centered) for single items?
  - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.

  - menus: local shortcuts, global shortcuts (#126)
  - menus: icons
  - menus: menubars: some sort of priority / effect of main menu-bar on desktop size?
+ - statusbar: add a per-window status bar helper similar to what menubar does.
  - tabs
  - separator: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y)
  - gauge: various forms of gauge/loading bars widgets
- - color: add a better color picker (perhaps a popup).

+ - color: add a better color picker
+ - plot: PlotLines() should use the polygon-stroke facilities (currently issues with averaging normals)
  - plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
  - plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
  - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
- - file selection widget -> build the tool in our codebase to improve model-dialog idioms
+ - applet: file selection widget (as an example)
  - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
  - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar).
  - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.

  - text edit: centered text for slider as input text so it matches typical positioning.
  - text edit: flag to disable live update of the user buffer.
  - text edit: field resize behavior - field could stretch when being edited? hover tooltip shows more text?
- - tree: add treenode/treepush int variants? because (void*) cast from int warns on some platforms/settings
+ - tree node / optimization: avoid formatting when clipped.

  - textwrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (git issue #249)
  - settings: write more decent code to allow saving/loading new fields
  - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file
  - style: store rounded corners in texture to use 1 quad per corner (filled and wireframe). so rounding have minor cost.

  - focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
  - input: rework IO to be able to pass actual events to fix temporal aliasing issues.
  - input: support track pad style scrolling & slider edit.
- - memory: add a way to discard allocs of unused/transient windows. with the current architecture new windows (including popup, opened combos, listbox) perform at least 3 allocs.
  - misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
  - misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
  - style editor: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space?
  - style editor: color child window height expressed in multiple of line height.

  - optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
  - optimization: turn some the various stack vectors into statically-sized arrays
  - optimization: better clipping for multi-component widgets
