resize window on "add to Collection"

When I click save and add to my collections, I can only see 4 of my listed collections, and 4 that I can contribute to.
It would be nice to resize this window in settings so one can save my images to more than 4 categories quickly without lots of scrolling. I would like to have a lot more sub collections, that each feature a subject I am studying, but have not expanded due to the amount of scrolling needed.

Being able to turn off "collections I can contribute to" would be nice and open up space as well.
