[Feature] Preference option to not have the Inspect window on the right side

[rkrejci]

First, thanks for the ART!

I'm using ART on a graphic tablet and one of the first tasks when processing photos is to go through the photos and select the promissing ones to be further processed (or the other way to remove those not worth the further work). I do this in File Browser using the inspect window. But the window with thumbnails and all the ranking, labeling and trash icons is on the left side. With holding the tablet pen in my right hand, I'm still moving it over the inspect window to thumbnails and back. It would be great to be able to switch the thumbnails and inspect windows or at least move/show all that ranking, labeling and trash icons (for the open image) to the right of the inspect window.
