The main description should include: "You can choose a set of templates saved in your sandbox space by using an appropriate sandbox prefix. For example, if you want to preview a version of Template:Test that you have saved as User:Foo/sandbox/Template:Test, use ''User:Foo/sandbox'' as the prefix." That's the "templatesandbox-text" message in TemplateSandbox.i18n.php. Also, right now, 'templatesandbox-page-or-revid' => 'Either page or revid is required.' I'd like to make this more readable by spelling out "page title" and "revision id".
Assigning this to myself because I'd like to use it as an example in a demonstration on November 29th for https://www.mediawiki.org/wiki/Meetings/2012-11-29 .
Fixed in Gerrit change #35957.
The second thing I wanted to fix is now fixed in Gerrit change #36182 which is awaiting merge.
Merged.
