Automatic startup of the gateway page in a browser, using something like
'netscape -remote OpenURL(gateway.html)'

Make htl and other client options configurable on a per-request rather than
per-invocation basis (by passing more parameters from gateway.html)

Add metadata inserts.

Warning/disabling of links to images not stored on Freenet - since these
could be used to track accesses of pages on Freenet.
[What, with automatically inserted Javascript? Or first it takes you to a
warning page which contains a link to the real page? Or a setting in
FProxy to filter out outside links or else replace them with someting else?
 - Brandon]

Rewriting of links as necessary (e.g. add appropriate prefix or form
parameters [?htl=10&key=...] to target URLs, resolve "../" relative links)
