[Feature Request] Select and Deselect All #161
Description
Hello! Really appreciate this program!
I just have one hopefully small request to be able to select and deselect all files.
The use case I am facing in particular is I have a folder of 60+ files, and maybe 1 or 2 have different subtitle track ID's. Its easy enough to deselect the 2 files with differing subtitle tracks and Mux set the rest of the files with the default subtitle track I would like, but going back to work on those single 2 files requires me to deselect the other 58 files one by one.
That, or there is some miss on my end that makes this easier than the way I am doing things.
Thanks for taking a look!
