Hi @jcrummy, and all,

Thanks for your report.

As mentioned on the doc.:

You can use the note top of and note bottom of keywords to define notes related to a single object or participant (available only for concise object).
See: https://plantuml.com/en-dark/timing-diagram#d50d8f9219a41435

[Ref. QA-6877]

Then it is now a wanted feature. 💡
Regards.

Ah, thank you @The-Lum , I missed that it was only available on the concise object. This is doing what it is supposed to do, then.

I'm ok closing this unless you want to keep this open to deal with it being a language exception and not a syntax error.

This should work better with last beta.

You can test it and tell us what you think about it!

Thanks
