With the rise of tablets that can use a digital pen (Microsoft Surface and iPad Pro) it would be nice to see a Logos app that allowed organic markings and highlights. This morning I tried this out on my Surface Pro 4 by copying a portion of Scripture from Logos in to OneNote and I loved the experience. It kept me much more focused than highlighting via mouse-drag and 'y' (or whatever your hotkey is). It felt much more like I was studying the Bible back in college, without the distraction of technology or the mediation of a program being between you, the user, and the text of the Bible.
Here is a small Sample of how it looked.

P S. Logos really needs to make that Windows 10 universal app.
