I respectfully suggest you consider enhancing Acrobat DC’s current annotation and highlighting tools to enable users to markup documents directly and instantly and do so without putting your users through Acrobat DC’s 28 tool / function menus.

I have been using Acrobat extensively for over 20 years and have a continuous need to annotate a wide range of PDF documents – legal, financial and technical and more. My annotation needs are both textual and graphic. While I remain loyal to Adobe Acrobat, I find Acrobat DC’s current annotation and highlight tools visually weak, limited in graphic capabilities and VERY timer-consuming to apply.
The fight for shorter and shorter reader Attention Spans: Very frequently, the recipients of my annotated PDF documents fail to visually catch my Acrobat DC annotations. These are “thin” and difficulty to catch. This is a real growing problem that is only getting worse as most readers mostly scan documents in shorter and shorter intervals and miss these highlights. I am almost sure that I am not the only Acrobat user that is dealing with this problem.
What I firmly believe is needed is a new set of modern annotation tools capable of inserting stronger / bolder annotations and with far less end-user efforts. An ideal example would be to modernize Acrobat by add the highlighting and annotation capabilities of SnagIt. This famous application gets the job done gracefully, based on its well-designed markup tools and their exceptional accessibility and ease of use.

I do realize that such a suggestion might have significant engineering implications. However, a tool as important as Acrobat needs to keep up with today’s need for visual richness that can help deal with the shorter and shorter reader attention spans of today's smartphone obsessed users.
