I’ve thought about this so many times before, but i have never put the request into words. Thanks for doing that!
My (similar) usecase: i know the target topic for the particular posts that i want to move, and have it open in a different tab. It’s much easier to copy the target url (AltD + CtrlC) and paste it in the move modal instead of having to type the name of the post, then search through the multiple results discourse returns.
