title and the edit summary, rather than using wpSummary for both.

Krinkle is saying there should only be one input on the section=new form, but it should have a different id: "I'd expect the script to be unable to find a summary and do nothing."

EditPage.php can now handle separate section titles and edit summaries (as of 1.19). It should be rather trivial to change the edit form to take advantage of this.

Adding "easy" keyword then.

I want to work on this bug. I get the idea that only an extra section title field has to be added to the form. I presume we only need to add extra methods along the lines of getSummaryInput,showSummaryInput,... in EditPage.php, to show the section title field in Edit page and call the newly built showSectionTitleInput() in showEditForm()?

I suggest to add the existing <input type='hidden' value="..." name="wpSection"/> an id. Because this seems the only (optimal) solution to check with JavaScript of this page status. The alternative not optimal solution would be per jQuery:

if ( $( "input[name='wpSection']" ).find( "input[value='new']" ).length ) { /* new */ }

The other not sure possibility would be (not recommended):

/&section=new/.test(location.search)

I figured out now, there is no problem here with JavaScript. You can simply check

$("#wpMinoredit").length

to proof the new section summary (because there is no).

Trying to explain this for a contributor, as this is marked as good first task:

Going to e.g. https://www.mediawiki.org/w/index.php?title=User_talk:Malyacko&action=edit&section=new , there are:

<span class="mw-summary" id="wpSummaryLabel">
 <label for="wpSummary">Subject:</label>
</span>
<input class="mw-summary" id="wpSummary" maxlength="255" tabindex="1" size="60" spellcheck="true" title="Enter a short summary [Alt+Shift+b]" accesskey="b" name="wpSummary">

Going to e.g. https://www.mediawiki.org/w/index.php?title=User_talk:Malyacko&action=edit&section=1 :

<span class="mw-summary" id="wpSummaryLabel">
 <label for="wpSummary">Summary <sup><small>(<a href="https://meta.wikimedia.org/wiki/Help:Edit_summary" class="extiw" title="meta:Help:Edit summary">?</a>)</small></sup>:</label>
</span>
<input class="mw-summary" id="wpSummary" maxlength="255" tabindex="1" size="60" spellcheck="true" title="Enter a short summary [Alt+Shift+b]" accesskey="b" value="/* Some preset text for the edit summary */ " name="wpSummary">

And as Perhelion already wrote, for the time being, in the second case the following item also exists and could be checked for, as a workaround:

<input name="wpMinoredit" value="1" tabindex="3" accesskey="i" id="wpMinoredit" type="checkbox">
