First, I should say that Planeshift is awesome. =)

I do have a suggestion, though...

As it is, when you press and hold either shift key, you run rather than walk. I would suggest perhaps making the shift key toggle the runmode on or off, rather than requiring that you hold it down.

Why? Well, perhaps it\'s just a matter of personal preference, but the less keys I have to use, the happier I am as a gamer.  

I did a search and didn\'t see anything related to this, so I apologize if it\'s been mentioned.
