modifiers clipboard

Hi guys, how´s going?
is it possible to someone write a script similar to this?
this is a modifier clipboard, very useful, but it has a UI problem in max 2019, and it seems the developer is not updating the script anymore (at least he doesn´t answer the posts in scriptspot).
I really don´t know how difficult is to do this, so if it is hard, don´t bother trying.
