This screenshot shows small red icons next to all of the elements that have events assigned to them called (Labels), the idea is that each element will soon have different types of icons associated to them that indicate what events or triggers, etc are attached to a button, graffic or text element.
The new properties, image tab now has button state previes and a file folder structure so buttons and skin elements can be organized, not shown are the copy and paste commands so you can move items between folders.
Some other items to mention are improvements to the xLobby client server system, lighting services, some music playlist bug fixes. New features and events related to speech and music playback.
More information will be posted on the release scheduled for tomorrow.
