Ok, I am a new user but I will give you my honest opinion, from a new user point of view...
I hope to be able to update this thread, although this doesn't seem to be a thread, as I discover new things, good or bad.
- The action on clicking on a file in a directory using the Shift key (to include more than one) reacts differently when you click on the icon beside the filename (the one that produces the checkbox) and when you click on the filename itself... I don't know how to explain it better than this but play around with clicking on different lines and you will see... If you need further clarification, please ask me.
