For starters, I know there's been complaints about this before, (<a href="http://community.roll20.net/discussion/702/token-movement-distances/p1" rel="nofollow">http://community.roll20.net/discussion/702/token-movement-distances/p1</a>) but there needs to be a 3.5 toggle for diagonal movement. It is core gameplay mechanics and sort of important. However, that's not what I'm here to ask specifically.
I would like the ruler to appear as you move your character. It skips an obnoxious step of having to measure, remember and then putting your character in that exact spot. Again though, I'm pretty sure this has been discussed before.
But a small suggestion I do have is having a shortcut pointer when pressing spacebar. A simple arrow following your cursor, that everyone can see. I know I could use the ruler for that, but it's rather flowbreaking having to exchange tools all the time.
I don't want the ruler gone however. It is very much of use for ranged attack or magic. I also love the aura, maybe even having a circle ruler in its submenu for grenade-sorts of damage.
