If you put item in the store. everything works pretty fine.
Until you press "SAVE" Then your complete in the dark what happens.
Is it uploading ?
Is it published (well you get a notification about that)
But your always look in the dark if it's started.
A progressbar or some other feedback that it's doing something and you need to wait would be a very use full functionality
The first time i pressed a few times the big red button,
because it looked like it did not do anything !
