So I just discovered that .txt files preview differently from other files in macOS preview. [love]

This request is (if possible) to treat .md, .markdown, .taskpaper, .mmd and other text based files as .txt files and use that preview.

I will make sure it's documented.

I'm not sure what's being requested here -- but I wouldn't want TheBrain to be overriding or ignoring any QuickLook setting on my machine.  For example, I have a markdown QuickLook generator installed that I like.   I don't want markdown preview as .txt.   Previews should work the same way in all apps.  E.g., DEVONthink uses whatever preview method is configured for that file type on that machine.

  1. Dang it, I totally forgot about QuickLook Plugins. Installed, thanks Korm!
  2. After installing, it didn't affect my preview within TheBrain (I don't know if it does yours, if so, please let me know). I'm assuming (and am prepared to be proven completely wrong here) that this means that changing what TheBrain uses in it's Preview wouldn't affect Finder QuickLook functionality. If this isn't correct, then please ignore this request, as I wouldn't want that either. [smile]
  3. To see the different behavior, attach a .txt file to a thought and then preview. It basically looks like a note window, except with no edit capability. Or at least it does on macOS Sierra.

Text files are rendered directly by TB9 instead of using QuickLook, as are HTML, PNG, JPG, and GIF files. For other file types TB attempts to use the native OS previews (except on PDF which on Windows we also render directly but this doesn't work on macOS, so that is left to QuickLook also).
