Beautifier contains a setting to compress multiple blank links. I'd also like an option to trim trailing spaces at the end of the code lines. That is essentially RTRIM().
The PL/SQL Beautifier trims all trailing spaces and tabs. We do have an enhancement request to remove trailing spaces on the fly while you are editing.
Sorry! That's just what I wanted, but didn't even notice. If you care, that's partly because doing Select All (Ctrl-A) highlights the whole line, not just the text. So you can't see if there are trailing spaces or not.
