Delete trailing spaces on saving a file? Fine, #KDEKate. But don't delete trailing spaces when I use a #NoBreakSpace.
I write text in the editor and then paste it in sites, and two of the sites I do that on have been updated to delete blank lines. The only way to preserve them is to put a #HardSpace on the line that's supposed to be blank.
If I unthinkingly hit Ctrl+S to save the file after I've methodically inserted a bunch of non-breaking spaces, they vanish. That's annoying.
I really wish you were better, #Kate. Please give me the abilities I had in The Semware Editor on Windows. Abilities you lack, least annoying of the Linux text editors I've tried.
