The UX needs some improvement yet.
Updates folder upon navigation (up, back, forward, in).
Also introduces a new button to refresh the current folder view when pressed or when hotkey pressed (F5 or ctrl+R)
With this commit we've definitely removed the target buttons to apply a
filter in current cel/layer/frame (which never make too much sense to
the end-user), and now we can just select the range of
layers/frames/cels where we want to apply the filter (like Flip and
Rotate commands that were already working in this way).
