It seems that the branch is conflicting with the current master, could you take a look?

Feature works fine but is not good-performant. The process to discover is the same as before (so, correct) but the complete discovery in accounts with great amount of folders is pretty slow. Just an example

Account with:

~13.000 folders +20.000 files

took longer than 3 hours to be completely discovered. As first approach is OK, because the given example is just an extreme one to test the app. But, probably, there are other ways to do this task in a more optimal way like depth infinity (needs server logic as well).

Other feature (not a bug): If server connection is lost somehow during the discovery process, this is never completed and there is no way to retry/trigger it because of the removal of the circled arrow icon. Known restriction not to forget.

Finally we have a kind of feature-loss. Before, users could sync the account whenever they wanted, now, only posible in first login. That is a known restriction as well.

Let's move this forward, without forgetting the known restrictions
