Current Notification system is really really simple and "heavy" to use. Closing animation is buggy and doesn't work as I want to. To specify that, JS animation executes earlier than HTML Form to remove it from Database which seems like it closes, but after Form execution refresh the Toast is back up until you refresh the page manually or enter the page from other page again.
Solution
I think some Framework for that won't be bad idea, but I don't know about implementation of it.
Keep your ideas up and comment!
