@Gargron Not sure to whom should I suggest this, or where would it be appropiate to do so.
In the public feed in an /about page some toots have a "link" with the text "Show thread". Clicking there does nothing, as in the /about page there are no columns where the thread can be displayed.
* Not displaying "Show thread" in the /about page.
* "Show thread" links in the about page should open a new browser tab to the toot (the same as clicking on the date/time of the toot).
* "Show thread" links in the about page should open the thread in the same column as the public feed.
