Pen+touch whiteboard
Windows 10 currently has an awesome Whiteboard app meant for quick notes and sketches using touchscreen+pen. Currently we don't have any apps that come even close to it.
Some features it has:
- Only pen can be used for drawing, dragging with fingers pans it instead
- Even though it's svg, eraser button on the pen works like in a bitmap graphics editor and only erases the part of a line near the pen, not the whole line
- Lasso selection via the other button on the pen
- Ruler - can be moved with 1 finger/rotated with 2 fingers on touch, any pen input nearby it snaps to one of its edges - allows to draw straight lines like you would on paper instead of by positioning dots
- Pinch zoom support - sounds obvious, but a lot of our graphics apps fail right here
- Inserting text, images, etc
- And that's about it, it's super simple unlike Inkscape etc
There's Drawing, but it falls short on many levels: it's a bitmap editor, has rather poor touch/pen support and is way more complex than this idea already.
