Getting closer to the next beta release here - just finished implementing the initiative tracking tools, and have a very large chunk of the macro functions done. The only major functionality that needs to be addressed is the "macro library token" support, at which point, while there will still be minor areas and specific features not yet implemented (such as, say, regular expressions or hexagonal grids), I think it will be "major feature complete". For what it's worth, I'm saving the ability to act as a server for post 1.0 - I had originally planned to only have "client only" mode in 1.0, but being able to use it as a virtual battle map (without requiring an external server or even a network connection) is pretty awesome.
It is definitely interesting to see the approach that MapTools uses to accomplish some of the various tasks that are handled by character sheets in The Dicenomicon.
So the plan is to finish up the macro library tokens and get the next release to beta testers. Hopefully I'll be able to finish off the rough edges (there are like 300+ functions for the macro scripts, and it takes a while to go through them all!), fix bugs and deal with critical missing minor features. Hopefully there will even be time to polish up the UI some more...
The initial release will be free, with two separate "in app purchases". The first will give you the Dicenomicon style virtual dice, and the second will give you the ability to load campaign files that you've made (uploaded via iTunes "file sharing"). So if you just want a "client only" or a virtual battle map, it'll be gratis - how's that for a deal!
