The support for moving tokens via a ruler and via arrow keys should be up now and available for update/download.

I haven't updated the readme yet, but the basic jist is using arrow keys should work more or less as you would expect, but the size 2/4 tokens will move to the adjacent vertex in the direct you pressed, which half the time places your token in a place that isn't aligned. Every other move should be valid, or you could rotate the token 180° as well.

Ruler stuff works basically as normal for size 1 and 3, it just actually works correctly now. When you start measuring from inside a token that has the "alternative snapping" and the "even snapping" options set, it will make the ruler snap to vertices instead of the center of each hex since those are the points that make sense to move to for such a token. Pressing space will move that token and place the center of it at the vertex you were hovering over. I'm planning on changing this to require holding down a key so that you can measure to the center of stuff even with a size 2/4 mech.
