Aeon timeline is an awesome tool
MAC or WIN version and integrated with scrivener.
Tinderbox will blow your mind at how powerful it can be in skillful and non so skillful hands. It creates timelines for your needs and integrates with Aeon and scrivener and a lot else. The software is so powerful/versatile that it is hard to categorize it.
Scrivener is a lot of fun for writers and is the gold standard now for writing. Check that out also.
The benefit of all three for me is that they are independent botique, software produces. That specialize in functionality over fluff. Their customer service and integrity is first rate.
Good luck and if you find anything good yourself let us know.
When I'm talking about Zettelkästen, I always refer to the idea that Niklas Luhmann described in Kommunikation mit Zettelkästen. Luhmann emphasizes the ability of his Zettelkasten to surprise him with connections he hasn't considered yet. Following the references noted on his Zettel, he was able to lay out a "network graph" on his desk, pointing out interrelations visually. In my opinion, solely using notes in outlines is missing the visual cueing to build creative associations. This may not be important when primarily taking technical notes or using the Zettelkasten as a look-up knowledgebase, but when writing in Org-mode I always miss the opportunity to lay out Zettels in front of me. "Spatial" is probably the right way to name it.
Tinderbox for example is a tool that uses this non-linear approach.
Pen and paper, mostly, if it's physical. Annotations with Skim or Kindle app if not, then I export those notes to Tinderbox. Ain't cheap, but it's very, very powerful.
Tinderbox is your friend here i think,
Check up only one of the user that is using CSV on tinderbox.
It is a helpful forum so try there.
I came from the back end. Streamed vomit onto the keyboard until it looped into the..abyss..then stared at my creation and cried, cried, until the tears were gone, and I had to start editting, and pruning, and clipping.
At first I tried Tinderbox: http://www.eastgate.com/Tinderbox/
Spent too much time fiddling with it's unique query language. Had everything laid out, then abandoned it because it couldn't keep a proper format.
Finally switched to ywriter, laid out every scene and character, and suddenly, the giant turd appeared shiny and new again.
