I was thinking about the agility stat from Project MMO in relation to your dodge bar; most stats actually raise your other stats, with endurance raising your hearts / combat raising your damage / agility raising your speed. I thought that agility would fit really well as a stat that increases your agility bar over time just like with health, so here's what I propose:

Default Feather Count
-Make a config that allows modpack makers to set the default amount of half-feathers a player starts off with. For instance, 10 would start you off with 5 feathers. If "half feathers" is set to false, setting an odd number will simply round up to the nearest even number (a value of 7 would give you 4 feathers instead of 3.5).

Agility Integration
-Make a config for "Agility levels per extra feather" that defines how many levels it takes to get another feather. For instance, 10 would give you another feather on your bar at Agility levels 10, 20, 30, 40, etc. This would work the same way endurance does for max health, and agility does for jump height.
-Also make a config for every dodge stat, including dodge distance / immunity time / etc, and how much it increases per agility level as a percentage. This would work the same way combat experience works for base damage, agility works for movement speed, and endurance works for base resistance.

That's really all I need to suggest for this! Further integration is obviously up to you, but these are the features I think are really needed to fully add PMMO compatibility.

This is a really awesome idea, I still hope it gets added one day! :P

Side Note: Agility being rewarded on dodge is already a thing, since dodging counts as jumping.

I love this suggestion!
I'll see what I can do, thank you for the in-depth description of how to go about editing it :)

This could take a while to implement as I'll have to rewrite how feathers are calculated and rendered, but I doubt it will be an issue.

Thank you for your input!
