When you click on the button 'Save' in the profile - nothing happens.
Well, almost nothing.
If you look closely, then in the upper right corner something gets out and soon disappears - apparently, an analogue of notifications in the windows tray. ')
Just here this thing does not work as a visual feedback for the 'Save' button. Because the button is in one place on the screen, and the pop-up window is diametrically opposite. And it appears somehow “without pale”, in contrast to the notification in the tray - they usually get out with a bang, a crash and animation :)
The right guys draw a notice right at the button - where the user's attention is concentrated at the moment of pressing.
By the way, while I was writing a post, I got out a pop-up "There was an error in getting XML data . " WTF? It is wrong to make error messages. It is necessary to report that it was not possible to do, and not the technical reason for this.
