Generally actions in Nautilus were accessed through context menus or
keyboard shorcuts. However, those are not very discoverable and are
not touch friendly.

Even more, in list view it was not possible to access background actions
since there is always a selection, making Nautilus UX quite poor in that
case.

Also some actions were placed in the app menu, which didn't was not as
clear for some people given that we have most of actions in the toolbar.

In all, we came with a new design that solves the main goals of
discoverability, touch friendly and accessibility for background actions
and app actions, and now are placed in the toolbar together with an
overhaul of the looks of Nautilus path bar and search.

There is still work to do, specifically finding a design that works for
the selection actions and also to replace the current information
floating bar. The later might be just a different goal. However this
goes in the right direction.
