I don't know if the plug-in already exists but I've been using TextPad 4/5 a lot and it's really good to see all the files that's being opened. I don't wanna Ctrl+Tab first then see the file list.

also there're only 4 files displayed on the tab bar, why's that? I was confused the first time and then I had to Ctrl+Tab to see the full list.

This should be an easy to make plug-in I guess.
