I think if you just include the issue number in the list (without the markdown formatting), we'll get the title of the issue inline. i.e.
- #237

• Activate POST on collections #237

vs
- [#237](https://github.com/Kinto/kinto-admin/issues/237)

• #237

That links it to issue 237 in the kinto repo and not the kinto-admin repo. I couldn't find another way to do it.

🤦🏻‍♂️ my bad, got my repos mixed up, and that notation referring to this repo indeed makes sense.

I did just stumble on this though -- does this work in the description?
