I think notes is a very important feature in Dynalist. However, I found difficult to work text within it. First issue is that the font size remains small even as you zoom all in. I was used to WF UI were it goes bigger in relation to the title as you zoom in or smaller as you zoom out.
Another issue about font size is to get a good setting for desktop web and mobile. Sometimes I found a good font-size relation for the web but it doesn’t seems good for mobile.
Another issue for me is the lack for more markdown formatting to work with full text. A use a lot of markdown unnumbered list (-) and (>) comments in my texts and still can’t do it in Dynalist.
