I really, really dislike a folder full of previews, TOU etc. all on it's own. It somehow makes me feel gypped, a waste of time and space especially because 9 out of ten times those things are already in the main file.
Please no blinkie/store links, they're huge.
If you do lower and upper alpha, please name it differently so I don't end up having to do it. If I have to redo your alpha I probably will avoid your alpha at later date. ( I prefer one file for alpha not three)
Folders within folders within folders within folders drives me insane. I spend a ton of time deleting folders before I can 'play' with my new kit.
