This isn’t Ready!
Following designs are tentative art, far from a completed solution. There is a good chance to change, postponed for future releases or even completely dropped. In any case you shouldn’t consider these as final!
I also attached Files 3.6 for having a better view of the changes and because some people are on Files 3.4. Of course new designs are these on the left :)
Search bar on the center. The Google way or Gnome Shell way. I am big fan of large search fields and hater of buttons. Many buttons have been substitute by “links”..
Save button will “save” a search (not totally sure on this!). That means if you have a huge search over thousands files, next time you can just recall it and have it faster. Cached results (#325146) is bug that was filed 7 years ago.
Even More Stuff
Okay this is certainly an UI improvement! Although these 5 buttons on top right seems too much. What if..?
This is not going to happen (as far as I know) but I like it. Hidden Control Bars (like in FS) is something that many people would want it. By the way I hope to fix somehow “Tabs” which look ugly.
I have the simplest tastes. I am always satisfied with the best.
