I misunderstood the request, so here is the correct version as well:
It's a Pathfinder 1e extension that heals 50% (rounded down) of your remaining HP on a long rest (min 1).
Examples:
character with 10 HP and 3 wounds heals 3
character with 10 HP and 6 wounds heals 2
character with 10 HP and 7 wounds heals 1
character with 10 HP and 9 wounds heals 1.
It's actually an interesting house rule since it means the worse you're hurt the slower you'll heal.
Also another update to Ammunition Tracker:
Ammunition Manager v2.5
* 5E now counts arrows shot rather than arrows that miss (as per 5e rules). Thanks to Rivanknight220 for pointing this out.
* 4E now rebuilds ammo picker list whenever weapon details are expanded.
* 4E now counts ammo correctly even if weapon is fired through a linked power (requires "Power: Show item used" to be enabled). Thanks to kevininrussia for reporting this bug.
