Update 1.3 has been submitted to the Windows Store for approval. The primary feature of this update is ink selection and the ability to cut, copy, and paste the ink. I made some tweaks to the way the calendar gets centered in the frame which should make the app look and feel better as the window gets resized.
There are some issues with pasting the ink on mobile. I do not know if the APIs are supported on Windows 10 mobile because it is a small amount of code to copy the ink but for some reason the app will not paste. For now I have disabled the cut, copy, and paste buttons on mobile because of this issue.
I hope you are enjoying the app!
