There seem to be issues with the sheet. I've tested it in both IE and Firefox, and for some reason none of the auto calulation works and only a few of the auto-fills actually work. Here is a test sheet to show you what I mean. I love the idea of a Pathfinder sheet, but for the moment it seems that it doesn't want to work. If this is just a WIP problem that is fine, I can wait till you're done.
It is still an interim sheet because it's based off the old 3.5 sheet which also needs replacing. Whther it's a WIP or I call a stop there and continue with the new one I've yet to decide. With the need to rework all old sheets we didn't want to add yet another that needed redoing. That combined with the fact people kept telling us its just different skills and 2 boxes for CMB CMD explain the delay. It's unfortunate that nobody ever articulated the level of difference effectively, something I only realized after doing 2 days work on it.
Having said that the stuff I've worked on so far all works when I test it. Even in IE all the autocalc should work coz IEs JS engine isn't an issue, only it's DOM event handling and CSS cause problems.
Everything I've worked on so far seems to work for me. Only thing I'm not sure of is the class skills for the new classes as they're just a huge table of ones and zeros and
I know how to selects cols for command mode in vim. I couldn't figure out how to keep the col selected so I could type in it. If anyone knows how, or can confirm it's impossible please tell me.
Plugsy: I think most groups use the Medium advancement track...
If it's easy, I say include all three. If it's harder to code, just the medium should be okay, or none at all.
It's tough for me to say, I abandoned the XP concept a while back, preferring to let the DM decide when a level up is earned.
EDIT: Okay, looks like you edited out the XP comment...
