Hi,

depending on the version of the custom UI, you can modify the script script.menu.htm to add the list of commands that come from MOI.
This allows you to remove all these functions from the list to make it lighter.

I don't remember where it was, but I found a second file to have another list of scripts.
Splitting permit to have "your best-of" scripts and the additional and less used list.
I think it scan another directory where you can move te less used scripts.
