I'd be suprised if no one has thought of this before, but I'm actually in game now and I don't have time to run a thorough search....
What if they added a simple in game notepad that save to a .txt file??? I've seen other games do this and it makes a big difference for keeping track of important info in game. Radio channels, squad or player names, important bases, whatever would be needed is easily accessable both in game and out.
Now that I've said that, there might be some obscure function that does that already that I'm not aware of. If so please put my foot in my mouth. Otherwise, what do you all think? I would certainly use it, handily at that.
Please devs, give us more of a notebook/clipboard feel. Also, holding up the clipboard should really block out the sun glare. Important both for realism and handy playability.
Let me know what you guys think!
