That’s right, the plugin only implements freelinks, not aliases.

That’s definitely one of the options to explore for improving performance.

It’s possible to change which tiddlers are freelinked by customising the shadow
tiddler $:/plugins/tiddlywiki/freelinks/macros/view. This tiddler is tagged
$:/tags/Macro/View (a new system tag) which means that it will be included as a
local macro in each view template. By default, it’s content is:
<$set name="tv-freelinks" value={{$:/config/Freelinks/Enable}}/>
That means that for each tiddler the variable tv-freelinks will be set to the
tiddler $:/config/Freelinks/Enable, which is set to “yes” or “no” by the
settings in control panel.
Instead, we can use a filter expression to, say, only freelink the tiddler with
the title “HelloThere”:
<$set name="tv-freelinks" value={{{
[<currentTiddler>match[HelloThere]then[yes]else[no]] }}}/>
Or, we can make a filter that will only freelink tiddlers with the tag “MyTag”:
<$set name="tv-freelinks" value={{{
[<currentTiddler>tag[MyTags]then[yes]else[no]] }}}/>
Or we can combine both approaches:
<$set name="tv-freelinks" value={{{ [<currentTiddler>match[HelloThere]]
~[<currentTiddler>tag[MyTag]] +[then[yes]else[no]] }}}/>
(I’ll add the above notes to the docs).

It’s a pleasure. It’s an interesting problem and I am delighted to have been
able to welcome you back to the community with it,
Best wishes
