I am trying to think of a ay to identify tags on a tiddler whose target tiddler has not been created yet.
For example, I have a tiddler as follows:
This tiddler has a number of tags as shown. The tag Sassetas does not have a target tiddler that has been created yet. I am looking for a way to highlight tiddlers like that when viewing a data tiddler. That way, as I go through the TW, I can fix up any of those tiddlers over time.
Anyone got any suggestions?

[<currentTiddler>tags[]!is[tiddler]]
I’m not quite sure I understand this part, are you referring to “data tiddler” in this precise meaning: https://tiddlywiki.com/#DataTiddlers ?
Here are some things to try.
Use filter
[tags[]is[missing]!is[system]]
In the Advanced Search > Filter tab to get a list of all non-system missing tags.
Or add this CSS to a tiddler tagged $:/tags/Stylesheet to set a specific formatting for all tag pills of missing tags:
.tc-tag-missing {
font-style: italic;
}
Tags that have a “target tiddler” are assigned CSS class tc-tag-exists.
Tags that do NOT have a target tiddler are assigned CSS class tc-tag-missing.
So, to make missing tags easily visible, you can create a stylesheet tiddler (e.g., “TagStyles”), tagged with $:/tags/Stylesheet, containing something like this:
.tc-tag-missing { font-style:italic; font-weight:bold; }
Then, when you are viewing a tiddler, any tags that don’t have a target tiddler will display with bold italic text which will make them stand out from the other tags.

I use this filter:
[all[current]tags[]is[missing]]
Marked Eric’s answer as the “solution”, since it does exactly what the OP requested:
@EricShulman , thanks for your suggestion. I have worked out that the tag title display has its font style and weight altered when displayed in the All Tags list in the control panel. Not quite what I envisaged but all good nevertheless. I was hoping for an indication when viewing a tiddler and the tag in that tiddler’s tag list would have some indication, maybe a change of colour.
Anyway, your suggestion gets me much further much easier that before. So thanks again.

that’s exactly what it does. See my post above.
@CodaCoder , I can’t get that display on my TW. Don’t know why. For me the tag list is just displayed as normal. But I can get an italicised display in the All Tags list in the control panel.
bobj
@CodaCoder , done all that. I think there maybe some interference from other stylesheets I have defined. Will set up a test and see if that’s it.
Nope, removed all my stylesheets and viewtemplates but no different, the missing tag title displays just as normal, not altered.

Look in DevTools Inspector – right click on the tag, choose “Inspect” and you should see something like this:
If not, take a screenshot…
@CodaCoder here is a screen shot. Using Firefox on a Mac. Have searched for
strong text
Have searched for tc-tag-missing to no avail.

What version of TW are you using?
If you use the browser debugger to examine the tag (right-click on the tag and choose “inspect”), it should show that the tag text is wrapped in a <span> that has a class of either tc-tag-exists or tc-tag-missing which is added by the TWCore <<tag>> macro that is used to display the tags. This macro is defined in $:/core/macros/tag which contains the following definition:
\define tag-pill-inner(...)
...
<span class={{{ [<__tag__>is[missing]then[tc-tag-missing]else[tc-tag-exists]] }}}>
<$view tiddler=<<__tag__>> field="title" format="text" />
</span>
...
\end
If the tc-tag-missing class is not present, then perhaps you are using a modified version of $:/core/macros/tag rather than the default shadow definition.
Also, to confirm that your stylesheet is being applied, try entering the following into a test tiddler:
@@.tc-tag-missing This is some text that should be bold and italic @@
-e
@EricShulman the span is
This is the text of $:/core/macros/. I’ve searched for tc-tag-missing and it does not appear to be included. I’ve not edited this tiddler at all.
\define tag-pill-styles()
background-color:$(backgroundColor)$;
fill:$(foregroundColor)$;
color:$(foregroundColor)$;
\end

After I upgrade to version 5.3.5, all seems to be working as it should.
This might be a useful facility to retain in TW core, possibly via a user selection in the control panel.
