This is fantastic! The “dynamic paper” is really good. I agree that changing their size would be welcome… in general, the table size is too small relative to my screen and die sizes, if that makes sense. (For instance, on one of those “dynamic papers” I can only really fit two dice comfortably.)
EDIT: Although I see that zooming IN helps, since it makes the “screen” bigger without increasing the size of the dice. Hmmm.
This is really neat, and very promising! You can do a LOT of cool stuff with these “dynamic paper” tools. I agree that it should be possible to label each one on the fly: then you can use them to track initiative, hit points, dice pools, and for “moves” or typical rolls. (For example, if your game has a tricky way to roll for initiative, just make a “paper” called “initiative”, code in the modifier or whatever you need, and have any player who needs to roll that just click on that “paper” and hit reroll.)
There is a weird thing, though: when I try to add a text label, it immediately sends me to another website (thenounproject.com), every time. What’s that all about? Very strange (and means I couldn’t try out the feature). (I’m using Chrome, if it matters.)
