Sometimes it takes a lot of time to find a match and it is not productive to keep looking at the waiting screen. But the issue is, if we Command+Tab and do something else, we still have to keep checking if a match is found. The issue is, if we don't see the initial screen, we don't know who we are facing against in the Starting 5 selection screen.
If there is a Sound Effect which is played as soon as a match is found, it would be helpful. So, please play any sound effect when a match is found.
