- Allowing myself to browse an entire FQDN in a language, like the built-in FF feature or TWP extension
- Offer the option to keep the translate bar pinned/dropped down from the top
- Remember previous settings or allow them to be set ahead of time

Browsing forums or a site entirely in another language is painful having to ask for another translation each time, unless there's a feature that I'm missing. Think of message boards and forums for example.
Being able to set the translation per site, say foreignblog.com only needs fast translation for a quick skim, but foreignresearchpapers.com needs a "Best" approach for more nuance and accuracy.
