They said UI, so I don’t think they meant features. But honestly I’ve never been unhappy with their UI, aside from one day with multiple replaces across a few files where the autofill from clipboard kept deleting the expression I wanted to be in there as I navigated through what I needed to do.

But that was fine, anyway, it got through it and I’m just happy with the “apply to all open documents” setting. Saved me at least an hour.

The regex engine was not full featured last time I tried. Done know which implementation they use, but it was lacking basic features like end of line matching (if I remember correctly).
