This list can be incredibly long for particular titles (154 entries for "Talk:Barack Obama" at the English Wikipedia). The question becomes: does this list need to be paginated? If so, it should be moved to a separate Special page (similar to, but distinct from, Special:WhatLinksHere). If the results don't need to be paginated, the list is fine where it is, though it probably needs to be collapsed or something. It's simply overwhelming to the user.

This list actually should stay intact on edit page, because it gives lots of useful hints to user when editing. The simpliest usecase for instance: when replacing some template, some can be missed, thus preview will notify, that it is still present. OTOH, it may be collapsible or displayed per user preference though.

On a separate point: With enwiki at present, all current templates are always listed for a fullpage edit (even without a preview). For a section edit, the templates are only listed if the section is previewed, but the listed templates comprise only those in the edited section, which is usually more helpful than looking at the list for the entire page.

Presumably it would not be worthwhile supporting section-level information, such as ?action=info&section=1. So ?action=info would not provide all the information obtainable at ?action=edit&section={secnum}.

Therefore, providing information at ?action=info should not be at the expense of existing information at ?action=edit.

I think it's a really, really bad idea to suddenly remove this from the edit page.

Yeah, there a few issues that are quickly getting conflated here. This is mostly my fault (sorry). This bug should only be about whether to include the list of transcluded templates at ?action=info. Whether to continue to list templates at ?action=edit (and in what way) should be the subject of other bugs.

I'm updating this bug's summary from "Move "templates used on this page" from MediaWiki's edit action to the info action" to "Add "templates used on this page" to MediaWiki's info action". Do you think listing the templates used on a specified title at ?action=info is a good idea?

This is mostly bug 878.

This should be filed as a separate bug. Implementing the ability to get info about a particular section is an interesting idea, but far outside the scope of this bug. :-)

Yes.

(Thanks for refining the scope from "Move..." to "Add..." - much VPT drama avoided!)
