Is there a way to create, rename, delete scripts? There is a way to do this for scores using commands in the File menu, and it seems to me that there should be similar commands for scripts.
Also, when a script is run there is a great danger of wiping out or making drastic changes to the score one is working on. At least the user should be alerted when a script is going to execute a command that will erase the previous score.
A better, or additional approach might be, before IanniX runs a script save a temporary copy of the current score so that the user could load it to Undo the effects of running the script. In fact this might be generalized to allow the automatic saving of a user definable number copies of the score with the file names suffixed by a number to distinguish them.
