I've never heard of, or seen the tool, and I'm not particularly steeped in legacy software.

So I immediately got why this could be an example of "out of control UI/UX"... but immediately my eye was drawn to the bolded headings at the top of each section, and then the numbers next to them.

And so pretty much immediately after that it was clear how this worked: select the files I want to rename, checkboxes to select the transformations I want, and press the big Rename button when I'm ready.

Their redesign feels worse. Hiding the details of each transformation feels well intentioned, but it'd get very annoying having to open and close sections: never getting a full picture of the pipeline I'm putting together.

It also hides features I wouldn't expect to exist, like the Js renaming and translation.

I think if we hadn't let UI become implicit marketing and kept it highly HCI-driven we could have had the best of both worlds. But I guess the software industry decided we need new product releases to look different enough to warrant collecting more money, so we're deep down the current path.
