Can I turn it on if I am not selected?

@Patriccck, the A/B test will only be performed on the early adopter (test) wikis. As I can see, you mostly edit Czech Wikipedia, which is not on that list yet.

First, I would recommend enabling Vector 2022 in your global preferences. Then:

• If you go to Czech Wikipedia, you will see all our improvements, including the new table of contents.
• If you go to any of the test wikis, you will see all the previous improvements, and you will only have a 50% chance of seeing the new table of contents.

The big plus to Vector 2022 was regaining the ~15% of screen widthe taken up by the left-hand menu for displaying real content. If it now means losing ~30% to the ToC, with no way to turn it off, I'm switching back to the legacy Vector.

Subscribing so I can see when my days as a guinea-pig are over and I can switch back again.

The effects on screen width are really bad right now, I agree. I was also surprised to see that overflow of long titles is not handled at all at this point. Well, I'll be patient.

@Cabayi @XanonymusX please join us over at T306660 to discuss the issue of the table of contents on narrow screens. If you can include a screenshot, as well as details about your workflow (why do you make your screen narrow, do you need the table of contents when your screen is narrow, etc.) that would be super helpful.

thanks for this feedback. can you let us know what specifically is bothering you, and any ideas you have regarding possible improvements?

Well, long titles are simply hidden when they reach the right border; no ellipsis, not even some padding. The traditional TOC simply became bigger the longer the titles were. There are generally two options: overflow hidden with an ellipsis or word-break. I'm not sure what the best solution would be here, but anything is better than the current situation..

@XanonymusX interesting...long titles/section links should be wrapping. if not, that's a bug. can you include a screenshot of what you're seeing? for me I see this:

Ah, sorry, I should have said long words in titles! Of course titles wrap at spaces, that is not the issue.

ah ok, thanks for the clarification. I will go search for an example, however if you already have one please add a screenshot and a link here.
