I’d love to see simplified Permalinks/Permaviews, so that instead of
https://tiddlywiki.com/#Foo%20Bar%20Baz:%5B%5BFoo%20Bar%20Baz%5D%5D%20Qux%20%5B%5BCorge%20Grault%5D%5D
we would have the much more readable:
https://tiddlywiki.com/#Foo+Bar+Baz:Foo+Bar+Baz&Qux&Corge+Grault
and for plain permalinks, it would be much simpler, replacing
https://tiddlywiki.com/#Foo%20Bar%20Baz
with
https://tiddlywiki.com/#Foo+Bar+Baz
This was discussed in a thread here, a GitHub issue, an initial pull request and a replacement pull request with additional concerns handled. At the end of that last PR is a discussion of a broader notion of moving all permalink handling into wikitext, with a dynamic slug-building capability, where this idea might become the default implementation. I’m still fuzzy on the details of that, and I have no idea if such work might get underway anytime soon.
