Even though I've disabled it as much as possible and I'm not even using it, there is no frikken option to remove it from the tray. Peice of shit!
Luckily, you can disable it by editing "plugin_customization.ini" in "C:\Program Files\IBM\Lotus\Notes\framework\rcp".
Add the following line and it should no longer appear in the tray.
