I currently use OmniOutliner on my iPad for capturing all my notes, meetings ,tasks & ramblings. I currently use 2 Tags to broadly classify any actionables arising
Currently I transfer [Todo] & [Research] into OmniFocus and the entire outline (copy pasted) into Devonthink for searching later on.
Omnioutliner is super fast with keyboard (for me) to capture notes but searching is possible only in each file. I cannot do a global search for a [Todo] which meant I was quickly drowning in 15-20 files without knowing what to do.
My approach implies I destroy any outliner file as quickly as possible after moving actionable outside it.
Copy paste to Devonthink is not perfect , it’s difficult to copy paste back to Omnioutliner later on .
I would love to know how others are using Outliners/ Mindmap
