There are a couple of things that would improve the appearance and readability of the [[Special:Disambiguations]] interface.
- Use a table. TablePager would be ideal. The poor vertical alignment of all those arrows is horrible. Not sure what to do with RTL wikis; maybe reverse the columns?
- tweak the "(Edit)" buttons. Currently the brackets are also part of the link, which makes the button seem to run into the page title. They should probably also have the extiw class, not be internal links.
