More powerful management of ability scores

I'd really like to see ability scores, saving throws, and initiative handled in the same way that armor class is handled. I'd like to be able to track modifiers to ability scores separately from the base score, be able to define different kinds of bonuses to resolve stacking issues (spells like Mass Bull's Rush bring our game to a grinding halt as everyone has to stop and check if they have any other kind of enhancement bonus and then I have to create custom effects for each person), and have saves and initiative autoupdate when the relevant ability score is changed.

These functionalities already exist fro Armor Class, so we know that it is doable. The biggest issue that I see is that there isn't enough space on the character sheet to hold that many windows. My suggestion is to move these modifiers to a submenu that opens up when you right click on a stat.

As long as we're at it, a way to define relevant attributes would be nice. Like, Fortitude would be set to Con by default, but we could have the option to change it to Con + Cha for paladins, etc.
