After several hours played i have to say that it doesn't really feel like an Alpha. It's just serious fun. Having said that... ;) It would be great (especially my little finger will thank you) to allow a key-binding for a "double tap" to stay crouched permanently in addition to hold the crouchkey for a shorter time of crouching. Maybe another tap to the same key or a change to prone etc. or sprinting would release this "permanent action". Another very handy feature - as i know it from ArmA - would be the possibility to bind two-keys for one action. As example: Instead of holding SHIFT and W to sprint, just move your finger a bit "to south" and press W+S at the same time to sprint.
