Yes for the love of God, an Apply button that leaves the Rename window open without changing any settings, please.
Working on a long list of files or folders where I have to use a different regex each time - for example ^s(.) to \1, then on the same list of file/folders ^r(.) to \1, ^x(.*) to \1 ad infinitum. For EACH rename I have to 1) hit Rename button which I have put on a toolbar, 2) click Type: Regular Expressions, 3) paste and edit in the Old Name regex, or use the drop down to select an old one and edit, 4) do the same with New Name, 5) click Case Sensitive, 6) click OK and repeat.
Would save a LOT of time and clicking to have a good 'ol Apply button

As it stands, likely it will still take a while .. 
regretfully so.
