Kerbal Space Program

I don't know if this is intended or really bug, but it wouldn't be logical.

I exit a rover and enabling RCS, then walking around on that rover and suddenly sliding along of attached parts (low grav). I cannot compensate with RCS. It also can happen, that Kerbal is "stuck" in some sliding event (bouncing off a resistance or so, hangs in corner) where i cannot use RCS or even move. I need to move that rover to fix relative movement so the Kerbal gets a free stand.
Also, when exiting a roverhatch and releasing ladder, the Kerbal is wobbling around to find its stand. It should be possible to enable RCS at this point already i think.

I think EVA-RCS should always respond if activated, not just from a point the Kerbal got a stand.

I hope i was somehow understandable, i could provide a craft for mun where you could test some instances of described.
