This $12 plugin is small but super effective. If you have various colors or effects that you're unsure if client will like, you can turn them off with one click instead of going to each layer and toggling it off. For example I do a lot of gunfight scenes and some people prefer different looks to their muzzle flashes, fire, explosions, etc. So with one click i could turn off all the glow effects on assets, color tints, or whatever i want, all at one time if it was too much. Saves me so much time rather than going through all the comps. It also has a free version but for $12 the pro version has the ability to toggle the effects on/off in every comp in the project all at once. You can also do this with a Master controller if you know how to build them. This just saves time.
