The templates need a way to specify the size of the editbox that's created. I wanted to create a page layour template for defining our plugin help pages, to sort-of specify what type of information is expected... but one section that's needed is the whole "description" of the plugin, which is at least a paragraph, and another needs to be a sentence or two for "each" settings.

Working in the little boxes we're given now is so uncomfortable that noone will actually use them...

And for our settings, it would be awesome to be able to specify, in the template, that a certain section should be repeated one or more times, so I could define something like:
<dl>
<dt>Setting Name</dt>
<dd>Setting Description [Optionally, setting values:
<ul>
<li>value</li>
<li>value</li>
<li>value</li>
</ul>]
</dd>
</dl>

And have the whole section, and internally, the 'value' section, repeated as often as necessary for any given plugin.
