Hi Michael,

The line is there in Sidepane.htm. At some point I tampered with this file to keep the sidepane open and grouped like in my screenshot attached to my first post. That combined with Max's UI must have misplaced it to oblivion. But it's really no biggie, I rarely use the buttons anyway these days! Thank you for pointing me to the right direction but I really do not want to waste any of your time trying to figure this out. <3
