I’m trying to transition my “ToDo” list to a wiki, but it’s just not as convenient as a simple text editor. I like the idea of being able to quickly open a file, edit and save it. With a wiki I have to open my browser, navigate to my wiki, etc. I think it would be cool to have a text editor that allows you to directly edit a page online. That way you only have to enter a URL and your credential information once (if you choose to save it that is). Whenever you open it, just find your file, make your changes and save. The updates would be sent to your wiki.
Anyways, I’m sure this would be a fun project when I have time, but just throwing the idea out there.
