microplus: Added auto close when entering main menu
This changes make microplus' panel to automatically close when entering main menu.
The background is that when I was using microplus, I always had to press the close button on the panel, even if there was no reason to change the tpse for a while.
This was a little bad experience from a UX perspective, so I set out to find a way to improve it.
Here's what will do behave when take this change:
Also added note to side of close button for this change.
