I would like an option to cancel opening the secondary window in Bridge. As it is I can only"OK" the window to open and then close it. (I'm a klutz on the keyboard and often accidentally open a secondary window which sends me down a one-way path.)
I've moved your post from Photoshop to the Adobe Bridge forum.
Unlike Photoshop where the Photoshop team uses the Community forums for Ideas and Bugs, the Bridge team still uses UserVoice for feedback. Please post here: https://adobebridge.uservoice.com/
