How to make these go away faster?

There is not a setting that you can change in order to make them go quicker. Not sure if that is what you are asking. You can click that white X on the side to dismiss it right away.

I suppose I could make it so there’s a max of 3 - 5 on the screen or something. There’s kind of a long reason for why all of them get left now, but they really don’t need to be there anymore. Like @headrollsoff says, just click the X for now.
