Can you add an option to adjust the volume of the sound effect?

[Sweeper777]

At the moment the volume of the sound effect is the same as the volume of my Mac. I usually don't like loud sound effects so I need to turn my Mac's volume down before I start typing. But when I want to watch youtube or something, I have to turn the volume back up! So can you add a slider or something to adjust only the volume of the sound effect but not the master volume?
