SaiZai said:AFAIK, none of the suggested approaches are fully technically compliant; that Wizards hasn't yet threatened them does not indicate that they won't.
deltacoder said:what if you put all of the calculations into what are essentially "tooltips"? i.e. you move the pointer (or stylus for PDA) over a field and the calculation pops up?
Content such as feats, etc could also have tooltips - all human readable content, while not diminishing the power of the program.
SaiZai said:
Having the tooltip actually calculate the result would have the same problem; it's merely a minor detail of display.
Whether it would be OK to just display the formula, and have the user do it, is grayish; it is kinda pointless though in terms of usability.
