Please add a means of separating climbing over things, climbing on to things, jumping from ledges, ignoring of ladders etc. from Running. So you can run and have to tactically hold (or toggle) a key to perform these other functions when desired.
Oh and when sidling along a northern wall, sidling left requires pressing A while sidling right requires both W and D be pressed as only pressing D will disengage from sidling and this just feels bad.
