Icons of 3.5.1 on 3.5.4

Is it possible to have the icons, style of 3.5.1 on the 3.5.4 firmware? The new icons are not only only, but are against of productivity. Now it needs again time to get used to the new icons. And again, the new style is just ugly and very far from being professional.

Actually there wasn't a word in the changelog about the totally new design. This is unacceptable.
