Width of the right menu tray?

How can you change the displayed width of the right menu tray where the audio, art gallery etc is? I know you can collapse it, but I'm talking about how wide it is when its displayed. I somehow made it wider, and now it's taking up and annoying amount of screen space. & speak of which, can the collapse button on the tray be moved down to be visible when the page organizer at the top of the screen is pulled down?   Thanks

You can adjust the size of the side panel by pointing the the left edge and dragging it to the width you like.  Look for the cursor to change when you have the mouse in the correct spot.
