The sounds sometimes work and sometimes don't for me in MSBT. I prefer sounds or something more visual such as the screen tinting as I mentioned. Once those are in place, I'll keep the options since others may want it but I'll be removing any text notifications most likely.

I thought about that as I was uploading it. It works great for me but just because I use MSBT doesn't mean everybody else does. I'm going to add options such as bliz's default, maybe a few other addons if possible (which do you use?) and also an option to instead make the full screen a shade of some color.

As it stands now, if you have any mod such as bugsack or bigred to keep any errors from popping up you should be fine. You won't see a text warning but you will still hear the sound.
