So I was thinking...

Online games are quite a popular subject for klikers, and for the most part they're not too difficult to make, except for one bit - the lobby, which is a lot of hassle.

Wouldn't it be great if someone could create a "subapp widget" that you can just drag and drop into your game's main frame, that will give you an instant lobby (in the form of a modal popup window)?

Similar to this, but better presented, and with a few extra options like being able to set the maximum number of players per game etc.
