I wanted to make an extension command with two typeable string dropdowns (20 box type) where the list of the second dropdown will change depending on the selection of the first box. Something similar to the OBS type box. I managed to use the 25 box type for that, but I got rid of the 'typeable string' of the first box in the process. It would be great if a listener is added for when users select options from extension commands so we can replicate the behavior of the OBS type box.

Even besides the case I mentioned, I think a listener like that would expand the possibilities for extension commands. Making them more dynamic.

PS: sorry for my English.
