Logic block's open algorithm need to be improved #151

If you move a logic block while the vp note is closed, the logic block is added to the vp note even though the vp note is closed.
Also it is difficult to recognize that you need to turn on vp note when you first encounter it.

Slide the logic block to the side to immediately bring up the vp note.

Increase the visibility of the window that opens the vp note and prevent interaction when the vp note is off.
