Request: Change file name to avoid illegal characters

[byronetodd]

Hi,
First, i love the app. It is super helpful for those who are online for most classes.

I would like to make feature request though. My lectures are dated. e.g. 3/4/2022 9:00 am. The slashes are illegal chars in windows so I have to manually change them. Its a small thing but it would be a great help.

Thank you!
