Comment 14 for bug 1171650

I'm uploading here a recent screenshot of Gtk.FileChooser as it is in Gtk 3.13. Using this as a baseline, it means we have the following issues in order to get this design more like our design:

* When not using actions in the headerbar (dconf option), Put the pathbar in the headerbar. Also add the file type filter selection combobox thingy to the action area (currently it appears above it which is why in this screenshot you don't see a top border on the action area)

* Add the grid (icons/thumbnails/whatever) view

* Add forward and back buttons

* Add categories to the source list

* Make the pathbar work like Pantheon Files.

* Miller columns (not in the mock but would be really really nice)

Of these, probably the easiest to upstream and biggest impact changes would be the first thing about where stuff goes when you're not using actions in the headerbar.

I think we might have to make some concessions about certain designs such as the grid view not being exactly the same as Files and without a lot of work we probably can't have the same pathbar as Files.

Something that might be more difficult is we have to find out why they decided not to use categories or present forward/back navigation. Adding views like grid and column would also probably be a lot of work and face design scrutiny. I wonder if it's possible to have views be pluggable somehow so that distributors can add/remove their own views? This would allow us to circumvent design disagreements in the views at least.
