Look inside Property List
It’s a tough time for me to figure out how to read file with type Property List (for tweaking purpose). I tried to use TextMate but it’s been expired. I also tried to use TextEdit but all I can see were mysterious codes. However, Quick Look seems to be working well with this kind of files.
