Key bindings for stance bar

[PigtailsofDoom]

I'm not sure if I'm missing something or if nUI just doesn't have this feature yet, but it would be awesome if we could assign key bindings for the stance bars. My main is a druid and I tend to switch back and forth every few months between trying out nUI and other interfaces. I noticed last night that I couldn't assign key bindings to my different shape shifts, which is something I really like about bartender/dominos. In some raid fights it's very convenient to just be able to use a key binding to switch into travel form to move out of fire quickly and then shift back into Moonkin form when I'm safe.

Also, this is unrelated but another question I wanted to ask. It seems like nUI uses up a lot of RAM. Typically it's around 15 to 20 but occasionally it uses up as much as 30. This tends to cause a lot of lag for me as I don't have a dedicated graphics card (and the graphics card is crap anyways but it's a laptop so I can't upgrade it), even with trying to lower the refresh rate as suggested on the faq page. When I was playing last night I was only getting 2-6 fps in Silverpine Forest, I usually get about 20 to 30 there. I don't want to know what my fps would be like in one of the cities or in Northrend... Is there any way to fix this or is this working as intended and I'll just have to deal? I am using some other add ons, but not that many... I also don't recall having this issue to the extent that I am now, when I was using nUI back in June.
