Add Sub Folders

[Noodle2damouth]

One feature that would really improve organization is the ability to create subfolders within folders.

At the moment, managing a large number of pinned tabs/bookmarks/workspaces becomes a little difficult without hierarchy. Subfolder support would make it easier to keep related items grouped together and quickly accessible.

Would love to know if this is on the roadmap or if it could be considered for a future release.
