# * Keep Aether linting, debounced, on any significant change
# - All problems just vanish when you make any change to the code
# * You wouldn't accept any Aether updates/runtime information/errors unless its code was current when you got it
# * Store the last run Aether in each spellThang and use it whenever its code actually is current.
# Use dynamic markers for problem ranges and keep annotations/alerts in when insignificant
# changes happen, but always treat any change in the (trimmed) number of lines as a significant change.
# - All problems have a master representation as a Problem, and we can easily generate all Problems from
# any Aether instance. Then when we switch contexts in any way, we clear, recreate, and reapply the Problems.
# * Problem alerts have their own templated ProblemAlertViews.
# * We'll only show the first problem alert, and it will always be at the bottom.
# Annotations and problem ranges can show all, I guess.
# * The editor will reserve space for one annotation as a codeless area.
# - Problem alerts and ranges will only show on fully cast worlds. Annotations will show continually.
