I would really like to see this feature, because I switch my mods frequently and most of them require some tweaks to key config (e.g. in TFR you cannot use CapsLock for PTT, because it interferes with the radio).

Also, when adjusting controls it's nice to be able to set a backup. If I decide to swap several keybinds to see if they work better, I would like to be able to go back without changing every single one of them again.

Plus, like many people mentioned before, it would allow us to create new profiles and share configurations easily (I guess you can still do that by manipulating files, but not everyone likes to mess with that stuff).

So please look into this feature. The key preset feature is already in the game, just give us an ability to create custom ones. It shouldn't take more than couple hours of programming and few more hours of testing and bugbashing, but it can save hundreds of hours for players. Thanks in advance :)
