I’ve updated bf_rename.
I recommend the hotkey CRTL+F2.
Now it is possible to rename multiple selected files.
The title shows the file to rename.
And the super cool new feature: CRTL-A uses the current text for the all or the rest of the tools in the selection.
This is useful if you have a branch which for example belongs to a Fire effect. Simply open the rename script, write fire and press CRTL-A and all tools will be renamed to fire with their proper short name as prefix.
