I have been using Note app for a week and found some features I need. Yes, my two cents.
a) Block copy and move, paste.
Select an area by dragging, then tap on Copy button. Paste button will paste the same stroke in the clipboard on the screen, still can move with dragging it, then Another tap of Paste button confirms it.
b) Stamps
Select a stamp image from images previously put in the Stamp folder, and paste it. It may be another layer between the template layer and drawing layer.
c) The configuration of the pen pressure and width of the pen.
It seems the pen width is in proportion to the pen pressure. But, in my case, the curve of the graph for them is more like a quadratic function since just having a little hard pressure will make the pen width bold suddenly.
d) Screentones.
2 color is ok, but need screentones !!
