Version v2.3 of the TikZlings is on its way to CTAN. Cookie will soon be in your TeX distribution :) 
Why should it? It's the way this is handled in LaTeX for 30 years, why should `hyperref` break this or be broken by it?
You typed a lot more code around the `secnumdepth` - of course this takes time! :)
`\setcounter{secnumdepth}{0}` and drop all that setup. MWE: ``` \documentclass{article} \usepackage{duckuments} \setcounter{secnumdepth}{0} \begin{document} \duckument[toc] \end{document} ```
Other users might have the same question and won't be able to find whatever solution you might get, because it is hidden in a chat somewhere.
When I use `\titleformat{name=\section}{\normalfont\sffamily\Large\bfseries}{}{0em}{}%` to make all sections unnumbered (like `\section*` but still show up in the ToC), how can I remove the {,{,sub}sub}section numbers from the ToC as well?
Yes, as they rightly say: > it brings people to talk to each other about it 😉
Argh! This solved a longstanding mystery. I had completely given up on it thinking its calculation is from another world! :joy:
@samcarter: I also can't think of any reason that this could be interesting... but who knows? Nevertheless: it brings people to talk to each other about it ;-)
I don't really know why the time intervals would be interesting, but for example the stackexchange chat does something similar: if there are breaks, it inserts "9 hours later… " (and similar) between the messages.
@samcarter: ah ok - got it! :) bit unusual, but once you know it... ;-) The exact time stamp isn't so important, as long as newest messages are just at the bottom ;-) thanks for the explanation!
These are the times between messages. Messages are ordered newest at the bottom, older ones further up. If you'd like to see the exact time a message was posted, you can mouse hover over the message.

Just a guess: do you maybe mean the time intervals between messages? 
To easier understand the problem: Can you maybe show a screenshot with messages not in chronological order?
general question: why is it, that the chat history is not chronological? hard to see the new messages...
Here is what π has to say to all the people who give unasked advice: 
Sure! Pop one of middle tiles off, use a screwdriver to loosen the screw, disassemble the pieces, reassemble them in the desired configuration, fasten the screw, put the middle tile back on. Easy!
@samcarter: I think it'll be a lot of fun - and I hope a lot are bringing some cubes with 'em... something different this time, not just sitting and listening ;-)
I'm very much looking forward to learn all about colourful little cubes next month :)
