Considering most of us likely do the bulk of our editing in Customize mode, it seems an unfortunate oversight to not have the Nik Collection and Export buttons as something that can be a pallet for the user to place wherever they wish. Or, possibly put another button near the top of the right column that will then open the column with those items (and anything else the user wishes to add to the column).
Yes. To increase the size of the image being worked on, I often hide the image browser , which then hides the Nik and Export buttons. I’m then must re-open the image browser to access the buttons. Besides, these two buttons seem to be associated more logically with the particular image being worked on rather than the image browser.
A single click of the File menu (in the Customize mode) will bring up the export options, including to Nik, to disk, and to applications. I don’t see how what’s being proposed here would be superior to this already-available operation. Maybe adding hotkeys would help, though.
