Desktop - login process
Login process doesn’t show any visual feedback, user doesn’t know if something is happening or not. User should be able to have some information that something is happening.
iOS - login dialog
Login dialog starts fully in the view. When login name is selected, the field gets focused and magnified, so the login dialog is not in the view anymore. I don’t think that the magnification is necessary.
iOS - grid scrolling
It seems rather wonky when user wants to scroll vertically there is still minor horizontal movement. Also natural movement of the thumbs is diagonal, so user ends up in bottom right corner of the grid.
