A couple of my favorite features are Attachments and Comments. I switched over to Wunderlist AGAIN! I really like the look and simplicity of Wunderlist. I want to mark something as and so when I am in the mood to read, or on my commute, I could get things done. Context became a bit of a struggle because sometimes I wanted to use it more like a tag. To really be good I had to assign to a project AND context for every task. I also felt that quickly adding tasks became a challenge. I was forever feeling like I was missing tasks in the view I cared about. It really helped me learn some new techniques. I even bought David Sparks great Omnifocus Video Field Guide. The hard part was, I never felt I was a master of Perspectives. I could really start to focus on what mattered and not feel overwhelmed by ALL of my tasks. The thing I realize I liked most out of Omnifocus was the flexibility to create perspectives. I went all in on Omnifocus for quite some time. (without a lot of adding/removing tags, moving notes, etc) My previous solution of using Evernote had so many advantages I loved but at the end of the day, finding a simple view of what I needed to be focused on for the day provide challenging. I have definitely forced myself to stick to my guns when it comes to making progress on tasks for work however I am perpetually tweaking my tools. I am that person who spends more time learning about being productive than being productive sometimes.
