Thanks for your answer!
In my opinion it should just be clear that multiple local vaults can be mapped with a single remote vault. For me this was the source of confusion, now I understand.
Two suggestions: on the “Account” page it would be nice to see a summary of all the vaults synced (both local and remote). Maybe with some info like number of files, size, etc…
The second one is probably more long term, but I think it could be super useful: users with a sync plan could be allowed to acces their files directly from the web (logging in in the account page in the website). I imagine it as a read-only feature, with the possibility to download single files or the entire vault (maybe as a zip archive).
Thanks for the great work!
