* Added trash can function * Tweaked status text to always be the same * Removed some open second note code * Edior always focuses on text now * Added some extra loading note messages * Notes are now removed from search index when deleted * Lots more things happen and update in real time on multiple machines * Shared notes can be reverted * WAY more tests * Note Categories are much more reliable * Lots of code is much cleaner
