It'd be nice to simply be able to use an anti-fire potion before it expires. Usually I'm not paying attention and one time I look and I have a minute left with my antifire and next I look back and I catch myself using like 3 sharks at ancient wyverns because I forgot and didn't re-use my potion.
Instead of having to use it as soon as it's done we should be able to use it whenever we please and it just resets to 5 minutes rather than it stacking with the remaining time. I hope this all makes sense :)
