I do not include the option of listing hundreds of filings on a page because a) this is intended for quick access rather than in depth searching, and b) because in the case of viewing ‘All’ companies, it uses up too many server resources.  When viewing filings for the whole sector, there is no link to the SEC site because there is no comparable page there.  Actually, viewing the most recent filings for the sector at a glance is one of the main things I simply couldn’t do at the SEC site and therefore drove me to write my own tool.

Filings are cached for approximately an hour, and refreshed automatically.  The sector-wide filings view can be slow during such an update.  I’m working on it.
