Thank you so much for making this script! I have an error that came up that nobody else has mentioned in the thread, and I'm stumped, because while I know what this error MEANS, not so in this context:

Traceback (most recent call last):

I am using Linux Mint and new to Linux, so am totally willing to bet this is something totally obvious that I just don't know.
