Import OPML with text notes (OSX )
TheBrain (as of version 220.127.116.11 on OSX ) doesn't import the text notes of an OPML document exported from other outliners on the Mac, only the headlines.
The only way to be able to import the text notes right now, is to open the OPML file in a text editor, and manually replace all occurences of the attribute "_notes" with "description" , save the file again , then import it in Brain. This is what support suggested to do to be able to have the text notes appear in the correct place, in the Notes section of Brain.
However , ALL outliners on the Mac (or at least those I own and use : OmniOutliner, Tinderbox, Tree, NeO, Curio ) export AND import OPML files the same way, by parsing the text notes in "_notes", not in "description", wich seems to be an idiosyncrasy of TheBrain.
Having to manually modify each OPML document before importing it in TheBrain is cumbersome, so please make TheBrain import text notes the "right" way automatically.
