Best external roster manager?

Jay_Ibero

I've been using this:
http://hook.github.io/champions

But it looks like it hasn't been updated since Green Goblin/Doc Oc, and the prestige values are all wrong for everyone from quake and onward. Are there any better options, particularly for computing synergy combinations? Thanks.

Sadly no known new roster management so far.
I'm sad too.
