Thank you for your work! It is great.
We appreciate the support you continue to offer make this work great, @Patriccck ^ _ ^ Some comments in response to the points you raised below...
Prototype has not auto edit summary (for example "new section") when adding section, but it is in the history.
Great catch. Here is a ticket or this issue: T270539.
It is also too long (see this section) when adding and publishing new section.
Ah, yes. This is frustrating. Fortunately, the slow leading is a result of the tool being run on a test wiki. Once deployed to production, the tool should load quickly. cc @Matma Rex in case he has anything he'd like to add here.
I wrote that probably before but the link for addng [sic] section is hard to find for newbies.
We agree. The work to make it so people easily identify the affordance for starting a new conversation will happen in T267444.
Note: try add new section for example here. Why is not launched New discussion tool?
The New Discussion Tool needs to support pages that have not yet been created, you're right. Here is the ticket where the work to add this support will happen: T270323.
