I'm really not sure that this pop-up is the best location for it. It is only shown once to people who didn't enable the beta feature.

But it's probably better if our designer @Pginer-WMF responds.

Could you (or Pginer) elaborate on "once"?
I clicked "Nee, bedankt" many times in the past, on the day I made the mentioned screenshot it was indeed gone for the rest of that day, today I clicked the same red link and the pop-up was shown again.
(Beta feature disabled here, any *.wikipedia.org/*.wikimedia.org/*.mediawiki.org cookies are whitelisted in Cookie AutoDelete (FF plugin) settings, never experiencing any session issues.)

Thanks for the feedback, Marc.

We are in the process of providing Content Translation as a default tool out of beta. This is a slow process since we are communicating with the different communities to better understand how the tool is working for them before exposing the tool to more users.

We don't plan to make improvements to the current invite for users to enable the beta feature, since that will be deprecated once the tool is available by default. Instead, we have a similar invite for wikis where the tool is out of beta (example, more context:T232372) that we are happy to iterate on and improve as needed.

I'm not sure I understand your request. Are you asking to show the specific article that will be used in the translation? That's something that we surface in the new version of the invite, but only when the tool has a reasonable guess. Note that from the title of the article the user tries to create it is not always possible to identify the corresponding Wikipedia articles in other languages. If you were asking for something different, maybe a specific example would help to clarify.

Regarding "show once", that is our genera policy on generic invites. For those implemented before global preferences were available, this was tricky to support so the invites may show more than once. With the new invite we applied the following policy: if there is a specific suggestion we show the invite. If there is no specific suggestion, the generic invite (to make the user aware the tool exists) is shown only the first time.

Then just FYI:
The Dutch wp community is gathering opinions (sort of our 'request for comments) on whether or not even allowing the translation of other Wikipedia articles, and if so, under what circumstances.

Very relevant. thanks for sharing.
Content Translation is a tool to support editors to create a first version of the article as a translation, and it encourages editors to review and check the contents to make sure the resulting output is up to the community quality standards. Aspects such as the machine translation limits can be adjusted to better serve specific communities. We are open to hear from different communities in which ways the tool can encourage the creation of good-quality translations according to their standards.
