Rename button (replace characters)

i remember seeing a way to make a button that replaces underscores with spaces, and one that would capitalize filenames and make sure extensions were lowercase, but i cant seem to find them now. i am sure i am gonna feel dumb once its pointed out, but its starting to frustrate me.

You probably saw them here: ... amepresets

i was right, i feel dumb now. i was certain it was in here or on the main site. thanks again.
