Org mode is Emacs' PIM (Personal Info Manager). It includes an implementation of GTD.
Textmind's philosophy differs from GTD, so it adapts Org mode's behavior accordingly.
A robot can do and "think" about one thing at a time. A human cannot. Therefore the single-task assumption inherent in Org's workflow is unnatural. The application of human ingenuity to a task makes it evolve as it proceeds, rendering precategorization both counterproductive and frustrating.
Instead, Textmind is built around the chronological daily log processing loop.
This heading compiles links illustrating problems with Org's current workflow.
