I tried Leo a few times and really liked it. Not a programmer, but have to sort a lot of information and academic writing. I read this list because I enjoy seeing the project development and enjoy Edward's leadership.
I have moved off of Leo and now use Emacs, mostly for org-mode but also for whatever else is useful. Emacs itself has features that I can't give up, or at least am not willing to right now.
I recall seeing talk of using Emacs as a front end for, but now I cannot find it in my old messages. Forgive me if I am using the wrong words here. As I said, I am not a developer or tech-jobbed/educated person. To the extent it is possible for these to things to merge in my life I would very much like that. Please consider this small voice for whatever it is worth.
If I am not remembering whatever was said previously, please disregard!
