Better code

[teamcons]

Performances:

• Delayed show only on startup
• Move Debounce to the NoteManager
• Maybe cleaner CSS (Highlights moved to the Themer instead of setting Gtk.Settings for each window on focus)

Clean code:

• Keep a NoteData for the window and use Binds
• Use changed() signal for each note to connect to, to signal saving
• Add Past Into New Note switch???
• Make Animated into a property with a Bind on the enable-animations setting
• Make Linter kinda happy (but keep column-style variable declaration)

Nice:

• A windows version. Installable without admin rights.
• ctrl + scroll to zoom unzoom
