Please add more Pen integration.
I have select button on my pen (from SP3) and in doesn't work.
Also I expect to use pen like pen, not like mouse. I want to be able to add some notes, drawings etc.
Work in progress: take a look:
See http://www.zetuniverse.com/blog/announcing-flight-13-of-zet-universe-insider-preview for Sticky Notes experience
Currently we support pen working exactly like a mouse; it's also quite useful to select a group of items and move them around the project space.
However, better pen support is planned. Stay tuned.
