It would be so useful to have a simple keystroke command, like the shortcut H in Lightroom, that would allow you to hide the U-Points until you wanted to see them again. As it is, they appear and disappear randomly, and it’s really annoying.
While we’re cannibalizing Lightroom, it would also be useful to have something like the L shortcut, which would render the whole screen black outside of the photo. (I can’t imagine they’ve patented this.)
