I had a number of display panel tiddlers, each panel displayed abstracts of
all tiddlers matching a filter expression (in this case, tagged with the
title of the display panel.) The display panels, however, needed to be
categorised in order that several different tagpill swarms could be
assembled for the UI (one swarm for each type.)
Using tags, this necessitated the use of a tag or system tag for each type.
These tags had little semantic meaning to the user, but showed in the tag
swarm at the top of the display panels; thus presenting an unnecessary
distraction.
I replaced the use of tags with a single system field, with a value
representing the type. The panels could easily be filtered on the value of
this field, but ordering of the pills in the tag swarms proved troublesome.
I resorted to sorting by 'modified', and creating the panel tiddlers in the
sequence I wished them to be displayed. This is not ideal, as to change the
order, they must all be re-created in the desired sequence (or the
'modified' fields of every panel must be updated by another mechanism.)
I have a workaround, but ideally, I would like to filter the panels by
field value, then sort them according to an ordered list. Ordering of the
titles would then require manipulation of this ordered list only, without
having to re-set the 'modified' field in the desired sequence.
Using fields, my requirement is to sort a list of titles generated by a
filter expression (other than by tag) by the order in which the titles
appear in another list.

That, I believe, sums up the requirement -- an alternative 'hidden' system
tags field, which does not display its tags in the tag swarm in the main
story river and doesn't clutter the user tag editor. This would be more
convenient than the use of a field, as all of the tools provided for the
'tags' field would become available for this field.
The problem is, that system tags still show in the tag swarms at the top of
tiddlers displayed in the main story river, and they have no semantic
meaning to the user as they are used only to arrange the UI.
Either system tags should be filtered from the tag swarm and user tag
editor, or system tags should be placed in another field entirely. I kind
of like the second option -- I think the idea of a system tags field makes
some sense. Separate system tags field, separate system tags display
(hidden from default display), separate system tags editor.
-- this might provide a more intuitive scheme for users (separates the
'clutter' of system tags from the usual UI, rendering both more
understandable)
-- enables the use of 'cleaner' tags for system purposes (no longer
restricted to $:/blah-blah)
-- reduces the number of tags in both lists (users will likely migrate a
number of tags into the system tags field)
I don't know -- what do others think?
