Safety logic or better UX when adding new sync directories

[kugiigi]

Description

I'm not sure exactly how it happened but I accidentally added my whole NC to sync on my device. I was trying to add a single directory and if I remember correctly, I tried to enter the name/label multiple times. When is the sync actually added anyway? What happened to me is that a correct entry was added but also another one with empty target NC directory and I guess it treated that as the root NC directory.

Hello @kugiigi ,
I can add a safety check for local empty path. I think somebody could wish to sync remote root - this would be legal case ...

Disabling a whole local home directory makes sense (it is actually NOT recommended in the readme/help), so we can programmatically disable.

Target is added when you push save. When you remove, it is removed. The synchronization is completely asynchronous to this - it is controlled by the backend daemon, so if you delete a wrong entry fast, it will not be synchronized.

Do you recommend any other paths to be included?
