After realising that Yanfly's Buffs States Core plugin didn't have any way of changing the way the "remove by walking" timer (referred to as "_.stateSteps" in the code) is reapplied like it does for a state's turn countdown, and that I couldn't find another that did, i decided to make a mini plugin of my own to do just that.
This is my first ever plugin, as well as a one I only intended to use in my game specifically, so it has pretty limited functionality. But since I struggled to find a plugin like this myself it couldn't hurt to post it here.
