Disable Undo List Permentantly

Hello. Since upgrading to the newer version of Opus my font scaling problem is now resolved, thank you. Now however as I scroll through the right click menu where it say's "new folder" an "undo list keeps popping up and getting in the way. I can click the red "x" and clears the list for a short time but it keeps rebuilding. How can I permanently remove the "Undo" feature forever? I can't seem to find the right place to disable this feature. Thank you. :unamused:

Can you post a screenshot to illustrate the issue?
