Make transition between current folder and search view smoother
The current transition is quite sudden and disorienting, we should improve this and make the transition smoother so it visually makes sense to the user what's going on.
The current improvements could be:
- Make the transition of window slots smoother
- Make some animated transition between listing the files and the files in search from the current folder
This is doable only in the new views, probably, since we will be sharing the same UI item model item behind.
