Textmind uses Spacemacs, Org mode, Magit, Dired and Treefactor to organize text. Emacs is an advanced text editor designed by hackers for hackers. If you're new to Emacs, it may take you years to become proficient.
Until you're proficient, don't rely on Textmind for production.
Paper inherently limits info volume. This helps beginners. Start with a paper GTD system. Rely on it, while using digital tools to supplement. Evernote isn't bad for transitioning from paper to digital.
When your digital skills are more reliable than paper, rely on Textmind, with paper supplemental. Evernote is still useful for scanning paper into digital.
Some are interested in using Textmind with paper and filing cabinet. I don't know whether that would work.
