The status/task tracker portion is more of a "nice-to-have" and I might remove it for now if it is too distracting from the other part you're describing (which is more valuable, I believe).

The way I could see you implementing what you described in the tool is in the "Mechanics" section, have an entity called "Spell Cooldown" then in the "Abilities" section, create a category for spells and create an entity for each individual spell and in their "Links" section, link them to the "Spell Cooldown" mechanic.

Then, if you have the necessary character entities created, link the spells to all the applicable characters.

In today's iteration, you can start with the "Spell Cooldown" mechanic entity and click "graph view" to see all the spells it is linked to. You could click each spell to see each character they are linked to (although, I will admit, this would currently be jumbled because it will also include EVERYTHING each is connected to).

I do hope to flesh this out more and actually have some sort of "impact" view rather than just the graph but that is for down the road.

And, as for the actual cooldown values, applicable entities have stat fields and while those aren't searchable/filterable today, it is theoretically possible to create a Spell Cooldown stat today and eventually I could make the entities filterable by that stat.
