* If you suspend your laptop, then resume, the network manager prompts you to ask whether you want to reconnect to the WiFi point which you were using before. Why? It doesn't prompt you at boot, just after a resume. Yes, of course I want to carry on using the WiFi I was using a moment ago.
I have never had that problem. Must be a problem with your configuration? File a bug or ask on IRC.
* By default, if you drag a window to the top of the screen it causes the window to be maximised. Yes, I know they copied this from some other desktop, but it doesn't make it any less idiotic. It's overloading a gesture to do something different, and leaving you no way to do the old thing which the gesture used to do. It doesn't even make it any easier to maximise a window, because you could always double click on the title bar to achieve the same thing. It does however mean that if you want a number of tall windows (making best use of your large monitor) you have to jump through hoops to achieve what should be easy.
Doubtless others can provide lots of other examples.
I always use Super (aka Windows-Key) + Click + Drag to move the window around. Then you don't have to grab the top of the window, it works on the entire are. Also try Super + Rightclick for resizing. Works on almost all window managers.
