We live in a world of nearly endless options for productivity and writing software. Personally, I’ve tried many. But sometimes the best solution is one of the simplest and oldest. For me, that solution was “downgrading” to plain text files as my primary means for note-taking, writing, knowledge management and life organization.
I've recently left Ulysses even because while it was "plain" markdown, it still had its own database for it's fancy features. This meant that I couldn't easily edit the files in anything but Ulysses and I want open workflows.
Now I'm writing in 1Writer, but I could easily use Byword or iA Writer without skipping a beat. My work is now more portable, which is what I want.
