That's a perfect and modern project/DLL, really good work.

I wanna suggest to add an option to set how many seconds we want the notification to stay visible before get hide in notifications bar

e.g: //noop $mToast.ShowToast(TEST,test message,$mircdirmain.ico,60)

60 = Will determine that how many seconds will the notification box will stay active before goes in notifications bar.

- Thanks!
