* chore: todo.txt * chore: comments * fix: no fast refresh on VME290 Reverts a line of code which was accidentally committed * refactor: god class Divide the behavior from the old WindowManager class into several subclasses which each have a clear role. * refactor: cppcheck medium warnings Enough to pass github CI for now * refactor: updateType selection * refactor: don't use a setter for the shared AppletFonts * fix: update prioritization forceUpdate calls weren't being prioritized * refactor: remove unhelpful logging getTimeString is used for parsing our own time, but also the timestamps of messages. The "one time only" log printing will likely fire in unhelpful situations. * fix: " " * refactor: get rid of types.h file for enums * Keep that sneaky todo file out of commits
