Opacity sliders are generally enough if to move them to zero. However, in this case you can do:
- Alt-X for the XP (entire) window
- Alt-C for the clock window
- Alt-N for the compass window
- Frame&titlebar=none for the target/implied target windows
- Frame&titlebar=none for the bottom bar (you could also completely remove _ProfitUI_BottomBar.xml for a slight performance gain - don't forget to add it to the ignore list on the updater next time you update)
