[FEATURE] Open Recent sub menu under File menu

[ABUDIYAAAA]

Is your feature request related to a problem? Please describe.
It’s sometimes hard to quickly reopen diagrams I was recently working on, since I need to manually browse for them each time.

Describe the solution you'd like
Add an “Open Recent” dropdown under the File menu (like VS Code) that lists recently opened diagrams for faster access.

Additional context
This would improve workflow efficiency, especially when switching between multiple diagrams.

ps: I would like to help build this if possible.
