Same way to the mod list works, you can ctrl-click several rows, then hit <space> and all are enabled/disabled together. Of course, also would be great to have a Select All/Deselect All as the ESP/M panel have now.
May I add the suggestion for a Toggle Selection? :)
Thanks!
Hrm.. this page doesn't seem to let me attach a file (permissions?), so I uploaded a patch that implements everything except the popup menu at https://sourceforge.net/tracker/?func=detail&aid=3168561&group_id=284958&atid=1207903
done the popup menu with select all/none/toggle selection - no keyboard shortcuts yet, I was thinking crtl-a/ctrl-d/ctrl? (really not sure about a good shortcut for toggle yet)
