Well! here I go:
Sugestion: add a button to remove files. Or a friendly way to remove them. I just right-clicked and there it was the option.
Anyway, after adding a folder, removing some files, the next screen "Register Com Objects" Still showed all files (before removing them).
And about not adding ScriptInfo.xml. I believe it is because of the first panel that asks for the information. But there is not all of it. What about commands and menus?
Ups... sorry!
