My current implementation of this issue fixes the problem where the notePads keep switching between dark and light mode while Hop is in dark mode. There is still an issue where, when switching to dark mode, notes that were in light mode stay in light mode until edited. After editing, they remain in dark mode until you switch back to light mode and edit them again.
