• The strokes of "Felt Tip Pen (Soft)" and "Dip Pen (Soft)" were lighted, so they were corrected to dark. Added "Add Opacity" switch. If this is turned off, a lighted state is also possible. If you turn off "Add Opacity" when using an eraser, it will erase weakly.
• Changed to a specification that determines the stroke when the Opacity Lock is switched when using the Bezier Curve Drawing tool and the Polyline Drawing tool.
• Removed "Uniform Eraser (Overlay)" and "Uniform Eraser (Saturation)" from the Basic brushes in the Brush Tool. If it has added to the Custom brushes in the Brush Tool, the Custom brushes side remains.
• Added "Uniform Eraser (Overlay)" and "Uniform Eraser (Saturation)" to the Basic brushes in the Eraser Tool.
• Added "Genius Pen" and "Stylish Marker" to the Basic brushes in the Brush tools (Brush, Eraser, Smudge and Blur).

• Added the cancel button on the alert which is shown after you tap the Brush Unlock button or after you use a locked brush. Additionally, now the app automatically select some brush which is not locked after you use a locked brush and cancelled the alert so that you will be able to draw a line in the next stroke.
