At the moment an extension is sorting the list through a tag (using a render hook?):
<sort2>
* C
* A
* B
</sort2>
Outputs:
- A
- B
- C
However, the result is temporary in that it is kicking in each time the page is loaded and this might have downsides as the list grows.
Can you think of another way to achieve the same?
Perhaps there's a way of saving the output to the wiki page/database.
P.S: Posted this here as the question does not seem a fit for SO.
