I had to enter a command line prompt to disgorge the contents of the AppImage, & still was unable to find the files in there. However, it’s not hard to download the Source code, & access the files through that. Not that a Newbie should be expected to do so, quite the opposite.
I also think I know how to “split” a thread, but it requires impersonating multiple users, & I don’t think this is important enough for that.
