Granular syncing of conversations

Currently, the sync conversations feature is a global one: I can either sync all my conversations or none of them.

As a TypingMind user, I want to sync only some of my conversations but not the others. One way to do it is to allow to sync conversations at the folder level. Create a setting for each folder to control its sync conversations status. Ideally, I want to decide which conversations to sync at the individual level, but folders are a good compromise. Also, it would add a nice feature to your newly added Folders functionality. Thanks!
