[FR] Backup/Export pinned content

[paulverbeke]

Firstly first: thanks for trying to maintain this app alive !

Is your feature request related to a problem? Please describe.
I've been using FastHub for many years and accumulated a lot of pinned repo/issues/PR/gist I access regularly that I'd hate to loose in case of a bad android upgrade, migration, dead/lost/stolen device

Describe the solution you'd like
I would love the current backup system including the pinned content.

Describe alternatives you've considered
I was thinking of using the star system in GitHub at first but:

• sometimes you star a project just for helping them with visibility of recognition, and not really using it at all. That makes for a lot of noises around your "favorites" repos
• the star view in FastHub doesn't have icons, really useful to find quickly the repo you want
• and obviously no issues/PR/gists

Thanks a lot
