I have been using Nebo for a while and find the composition and digital ink to text fast and reliable. I’ve recently downloaded LiquidText, but haven’t used it much yet. It’s supposed to allow you to have it open in a side window with another document side-by-side. You can draw lines between the two documents, highlight and quote excerpts from the primary document, and link to other pages in the primary document in your LT note. The demo video is nice, but, as stated, haven’t tested yet.
