As well as a couple of mind mapping apps (which I use when I specifically want to link out topics in a more spontaneous way or need to present to a room) I do continue to use outliner apps. Primarily these days I use Omnioutliner, though I have some older ones still on my devices by the looks of it; I must migrate that data at some point.
It has support for multiple columns and data types as well as plenty of prebuilt options for templating, exporting and styling. It also permits sorting on individual columns.
Mac Drafts development aside, there’s the cross device availability of the software and though I’m not using the pro version on my Mac, there’s a huge automaton potential there.
I do tend to use it for simple outlining as I have several templates for things like packing and recurring projects but for simple check lists I probably do create the in Drafts more often.
The thing that’s really useful in the app (and typically with mind mapping apps too) I think is the way nested elements can be collapsed and consolidated.
Whilst Drafts has me covered for quick, brief(ish) outlines, I turn to a more specialised app for helping me do that. It’s just like if I were writing a book I’d switch to Scrivener and if I’m writing tehnical documentation for work with diagrams and tables I’d be using Microsoft Word.
Drafts is a starting point for a lot of my content and with version 5 it takes me further than ever before, but there will always come a time when a more specialist app will take you over the line … but it quite possily wasn’t the place to get you started.
