My players can see a visual representation of a monster's remaining hit points (as well as the monster's name and any auras) without being able to control the token. It's a red bar that goes down as the creature takes more damage. This way they don't know the exact hit points but they can have some idea based on the damage they've done and how much the bar moves. I am pretty sure they can also see each other's health bars, but not exact numbers (except for the husband and wife who I gave control over each others tokens so they can cover for each other). On the advanced tab, I make sure that "See" and "Edit" are checked for everything (unless I want the monster to have a hidden aura, or name, or if I want to hide the health bar) but on the basic tab I make sure that only I as the GM can control the token. For the HP I make sure that the left and right values are both filled out, like 10 / 10 so it will display a bar. If I wanted to have a visual cue for something like mana, I could do the same thing with my 2nd bar, which is blue. When a player does damage, I just type in -5 in the red circle, hit enter, and the bar goes down. No API or macro needed. Am I misunderstanding the question? After re-reading it, it looks like maybe Toboe's problem with the bars is when using very large numbers? I would suggest you keep track of something like 375/390 by making it 37.5 / 39.0 ... in this case I think the bar will only update when the digits left of the decimal change, but it might make for a better visual representation of numbers in the hundreds. Although after testing I'm not sure it matters much, it's a percentage bar regardless. Remember that if you make any changes to token properties that are tied to character or monster sheets, you need to edit the sheet, delete the old token, and save the selected token again.
