I really like Kevin Lynagh's list of open ideas, and in that spirit it might be useful to list a few of my own. Kevin says it best:

I read a lot and want to remember (and synthesize) what I've read/incorporate it into my personal notes. More on ways I've tried to do this.
Basically, while reading a book on my Kindle, I want a low friction way to take short, speech to text audio notes that are tied back to my book and location. When I'm done, I want to be able to export all these to plain text to deal with later. These are just reminders, so high fidelity isn't critical.
Beeminder is a tool that helps you achieve your goals by charging you an ever-increasing amount money when you don't. It's very effective for certain types of people, with many calling it life changing, etc.

I'm a big fan of both vimwiki and vim-journal. The former is a great wiki/note taking system for Vim. The latter is a plugin by junegunn that mainly changes colors based on indentation level, folds at the list level and has a few other minor syntax things. I would pay (and have offered on reddit, fiverr and upwork) someone hundreds of dollars to make this. Barring that, I'm seriously considering learning vimscript to do it myself.
