New bottom-center notification popups - automatically close

[#1]

Description - the new bottom-center green and red notification popups do not disappear automatically and instead have to be manually closed via the "X" button on the notification. It would be great if these notifications could disappear after a specified amount of time automatically.

Why is this feature important to you - adding too many unnecessary clicks, and the popups end up stacking on top of each other if you neglect to "X" them out. This is especially noticeable when working on a complex report where you have to save and view the report, go back and make another small change, save and view the report again, etc. You can accumulate a lot of notifications in a very short timeframe.

How would you like the feature to work - either give us an option in Setup to specify how long the notification should be visible, or set the time limit for us. 

Current Behaviour - notifications have to be manually closed each time they appear.

Funny how we can put up with an annoyance like this and never think to ask that they auto-close them!

I've been working on a lot of reports recently, and this has become quite noticeable with all of the extra clicks I now need to do to remove the notification before the report will save the changes/updates.
