When I install a new application, I generally run it immediately. Having the new indicator might be nice to help find it - they don’t always drop into the menu where I expect.
I agree, I can’t see why it upsets the author so much. “You’ve installed a new app, here it is.” “YYYEEEAAAARRRRGGGGHHHHHHH!”
I know. Stop worrying about your computer and install Debian! It just works. It updates without a problem.
