The only snag with saving presets is I've never managed to work out how to delete them again. The manual says right click on a preset to rename, delete, etc, but it never works for me, and I can't find any other way to do it. I assumed they meant right click on its entry in the menu, but maybe they mean its name on screen. I only just thought of that now, lol. So maybe you could do a golden cursor for the place where the preset name appears on screen. If you click rename, it might even bring up an edit field wiht with the current name already in it, so that would be another way to find the name of the current preset. In Waves IR1, you can open those .xps preset files as a text, and just delete the data that refers to the individual preset, but the GTR one is just too complicated. There's just way too much info in the file.
