This is a significant improvement the colours make it so much easier to navigate and sync icon makes much more sense

.
A couple of minor points. Some of the icons lack contrast and detail, for example the integrity check icon on the main screen context menu is a orange blob with a few random red pixels at the bottom, using a screen magnifier I can see that it is rosette with red ribbons and a white tick, however all this detail is lost at the normal display size. Also in the modify profile dialog the integrity check icon different.
The mirror icon has lost its arrow indicating the direction of the mirror operation which I think is a retrograde step, personally I would be happy if the same icon was used for both backup and mirror as the difference between them a very grey area and the mirror is so small on the main screen that it difficult to see what it is.
I appreciate all the effort you have put into making these changes.
