DeaconPatrick, I am a writer as well and am constantly exploring new workflows looking to find the perfect one.
I suggest thinking through what your frustrations are with Finder and how DevonThink might solve them.
I’ve been using DevonThink most of the past two or three years, with occasional breaks to see if another workflow might be better. I’m probably all in for good at this point.
I write a half-dozen articles monthly, and use one Group per article or project. I store all my research materials in DevonThink–PDFs, archives of web pages, emails, interview notes, interview audio, PowerPoints, Word documents.
Most of the time I also took running notes in DevonThink, and wrote articles in DevonThink using Markdown as well, usually using an external Markdown editor such as iaWriter or MultiMarkdown composer. In my current job, before I send an article to my editor, I copy it to Microsoft Word, and then save a copy of the Word document in DevonThink.
For the past couple of weeks, I’ve been experimenting with using an additional app, Craft for running notes, bullet-type journaling, scratchpaper, and drafts. I’m using Craft in conjunction with DT, and plan to export projects from Craft into DT when I’m done. This is because Craft is quicker to use than DT, and the iPad/iPhone clients are MUCH better. It also makes it easier for me to experiment with Wiki-style organization (though DT also supports internal linking and wikilinks).
One of the signature features of DevonThink is that everything is stored in standard documents and folders. It’s very easy to get documents in and out and change around the organization to suit your needs. That contrasts DT with apps such as Evernote and Bear, which also let you export your work but exporting a lot of notes is a big project.
