Optimization of software exit function

[mting1117]

There are two kinds of exit function envisioned
1, currently open the software can directly open the canvas function, whether you can add a if the current canvas for the open state, open the software again can exit the canvas, convenient for some third-party software call.
2, in the toolbar is a long press drag, you can add a close button in the lower part of the screen, when dragging the toolbar is displayed, drag to the close button that is to exit!
