In the docs for the tags operator it says (my emphasis) …
The corresponding tiddler’s tags are retrieved (in order of appearance in the
tagsfield) …
which is not true.
tiddlywiki.com (5.3.2)
tagstest code:
The tags are <$list filter="[[$:/.rgt/bk/macro/flags]tags[]]"><<tag>> </$list>
I’d hesitate to call the outcome a bug – I mean who cares? – but the docs are wrong.
Looks like it is in order of the tags field to me on testing.
Original
Edit tags field to move edit-wide tag:
The tags display at the top of a tiddler is always in alpha order, I think. But the content of the tags field might be different. However, any manipulation of the tags field is likely to make the tags in alpha order again.
A-ha. Subtle but blatantly obvious now you point it out. Thanks.
