[FEATURE]: TUI - Session Picker - Organize into Virtual Folders

[diegohb]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

It'd be really cool to be able to organize session listing in the session picker by virtual "folders". A no frills implementation could be simply done by convention, group up session names that start with same prefixes.. or just use a delimiter like pipes?

This issue might be a duplicate of existing issues. Please check:

• Feature Request: Plugin hook for filtering session list in /sessions dialog #9553: Plugin hook for filtering session list in /sessions dialog - relates to organizing/filtering sessions, though via plugin API rather than UI folders

Feel free to ignore if none of these address your specific case.
