Hi there
Multiple Objects Rename is one of tools I made in [[ https://www.youtube.com/watch?v=RkQgul2xlMY | BsMax ]] add-on (UI Simulation) but I think this tool most be inside of blender. just simple and useful tool. specially wen i saw the new "F2" rename tool you added. this tool is same but when more than one object selected, open the second UI to rename multiple objects. I hope you found it useful and put it on Blender.
