It would be very useful if in TagScript exist the following:

1.- The property oldValue.

One more new feature is that developer can select the tags he wants to use inside the script.

In case I am creating a tag Change script you can select the tags that will fire the script, but when I am developing the script´s code there isn´t a place you can select the tagpaths I need inside the script.

I’ve also noticed the tag selection buttons are not present on all script editor windows. It would be handy if they were.
