The rough idea is to have a configuration dialog of sorts, with a list of "rules" and UI controls for adding new rules. Each rule would have a talent to warn about (multiple talents? talent tree?), a player property to check (race, class, talent, level, etc.), a target value to compare against, and a comparison (equal, not equal, has, doesn't have, greater than, less then, etc.). This will get more complicated if we want to allow multiple conditions in the same rule; "or" combinations could be covered by having multiple rules for the same talent, while "and" combinations would require multiple sets of UI controls for the conditions.
Other notes:
- Since we're talking about player-based rules for when certain talents are warned about, I assume we'll want these rules to be shared across all characters, which means the configuration information will need to live in either the world{} table or user prefs. Would we want to provide a "default" rule set for new users, to give them something to work from?
- For technical reasons, this one won't be easy to include in ZOmnibus; to make it compatible with the Plenum Tooltip addon, I'll need to give it a much higher addon weight than ZOmnibus uses.
