Synh DB logic not implemented yet.

1. when the file browser is opened elsewhere, the note cannot be deleted.
2. when we try to open the file which is already opened, opened file will gain focus.

2. controlpressed not refreshed after event done: resolved
3. New feature: rename, and when user is editing new file, asks to change name. Refuse empty string. Until they cancel, or give proper name, dialog keep appears
4. After sotring, delete/open did not work properly in browser: resolved

Menubar implemented with items. Save and Delete works now, but the other options is not working
