Right-Click on Buffs to pause buffs. And, Ctrl+Right click to pause all buffs. Community will love you. Tie it with Continuous Care if you have to.

Shift+Right click to delete a buff. Really Tedious when trying to swap from a draught to elixir rotation.

It could be exploited for infinite buffs, but if the pause on timer also disables the buff effects, it wouldnt be an unreasonable QoL.

Exploited how?

I just find it annoying to swap between tag and main to taxi my main so that I don't lose minutes from my furniture buff. If I can pause tent/church overflow so that I can get furniture again, it would be awesome. Same thing for NWs and Heidel/Furniture buffs (Esp with the recent furniture shortage). Otherwise, there are small gaps that make us rebuff or play the game without buffs for 5-15 minutes, which is just meh. I wouldn't mind the prices of buffs even going up to create an equal silver sink as before.

Rather than buffs lasting incriments of 60, NPC and House buffs should have an extra 5 minutes tacked on.  Church 305m house buff 185 minutes, Caroline 35, or allow you to spend more energy to get a 65, 185, 305 duration buff.  

Far simpler fix than adding a new system.
