The more I think about this, the more I'm convinced that I shouldn't do it.
For this builder, the best (and easiest) way to go would be to be able to right-click any item in any listbox and show a context menu that lets you open the relevant wiki page. This would require little data, since I can just look at the name to determine the appropriate wiki page. Some things would require extra data, but far less data would be needed than to add descriptions for everything.
For enhancements, just open the page for that tree, linked directly to the tier. So like Keen Edge would link to this.
The main strength of this planner is the streamlined nature of the data. Granted I entered a TON of data, all by hand, but it's really a drop in the bucket compared to how much data is in Ron's planner. All that extra data would slow me down (I have nobody helping, and I am not soliciting for help) to much slower updates after each game update. I like being able to post up-to-date data files within a couple days after an update, though lesson learned that I need to check in-game instead of relying on wiki 12 hours after an update goes live. heh.
For these same reasons, I think it would be a mistake to try and incorporate stats into the builder, like melee power or double-strike. It doesn't seem like much, but it's a huge, massive amount of data to enter and maintain. I think the original design philosophy of "less is more" is the right way to go.
I do look forward to the new version of Ron's planner, and keeping this one "Lite" while his is "complete" appeals to me.
