Bringing notes over from Devonthink into Tinderbox works pretty well in the current version of TBX 7.3.1.
It automatically displays the following KeyAttributes:
URL (populated with the backlink to Devonthink [which actually should be renamed to DT_URL, I suppose])
SourceCreated (displaying when Source was created in Devonthink)
SourceModified (displaying when Source was modified in Devonthink)
Then there is the SourceURL which is not auomatically set as KeyAttribute --> but it should, I suppose; AND: it should be automatically populated with – as the name of this Attribute implies – the URL of the original note in Devonthink … but it does not.
Is this going to change any time soon?
