When a mod adds persistent effects (in reality a repeating 0 sec effect) the info on the screen keeps blinking. It's quite distracting ;)

A request would be to have the effect text stay on screen just a tad bit after it is over to avoid that blinking.

Thanks for a great mod! =)

I'm not sure that I want to add any delays for these things as that would mean that the information on the screen wouldn't be accurate for a few ticks.

Instead, this sounds a lot like a design and performance issue with whatever mod it is that you're using. An example of a proper buff appliance is the vanilla beacon block that applies the buffs every 4 seconds for 5+ seconds. It doesn't have to last that long, but the buff duration should be always longer than the interval at which the buff is applied.
