It would be very helpful to get a pop up window when a game ends. They just disappear off of the list of multiplayer and may times I won't notice that a game finished.

I agree that would be nice.

The workaround I do, is look at the points page. That way I can see if someone surrendered a game (or was booted/eliminated).

You can also look at the 'Past games' tab and sort by 'Date ended'. Muli's Userscript makes this easier

Doesn’t the points from a game appear in the game summary, when you win a game?

The points appear on the game summary only when you open up the game that ended. I also look through the past games to find the results. It would just be helpful to be notified with a popup that says that your game has ended. Sometimes if you get killed early in the game, it could go on for a week or more before the game ends, and for you to be able to look at the history.
