You can draw a free stroke using left button dragging.
The system beautifies it when you finish drawing.
Red line is the primary candidate, and magenta lines are secondary candidates.
You can select another candidate by clicking a magenta candidate.
Primary candidate is settled when you click other area then magenta candidates,
or you draw the next free stroke.
Predictions
When you settle the primary, the system predicts the next drawings,
and shows predicted magenata lines.
If you like a predicted line, click it. The system generates next predictions.
If not, click somewhere else, or draw a free stroke.
If you click on a black line, the system generates predictions around the line.
Erasing
You can erase existing line by drawing scribbling stroke.
Note that what is erased is one closest to the starting point of the scribble.
You can also erase lines by click-dragging of left botton.
(click-drag is similar to double click, but not to release button after the second button down)
View Control
You can scroll screen using right button dragging.
You can zoom in/out using right button click-dragging.
