No immediate plans for an update, but I'm still using it and looking for ways to improve it. It also hasn't been downloaded very much, so I'm not sure if the effort is worth it.
Cam's last suggestion kind of defeats the purpose

I was trying to get away from power cards, and there are already a lot of sheets that are designed to use them.
For HazardCatcher's suggestion, I think it is more a sense of personal taste.
Since everyone's tastes vary, we see a plethora of character sheets. Some prefer a place for everything to be written in, some prefer a stripped down feel, some like to see all the math, some like ample free-form space to write things as they need them. Some would rather just use lined paper for the ultimate customized sheet.
A character sheet is like the gateway between the player and the character...if it doesn't work right for a particular player, its like the gate isn't open all the way to see the character on the other side.
