Thanks for your kind words and feedback!

A couple of your issues have already been resolved at least partially:

You can change the default search engine with `set searchengine [keyword]` and add new search keywords with `searchsetkeyword [keyword] [url]`.

You can change the newtab page (at least, the one navigated to with `*open`) with `set newtab [url]`.

This does expose another issue, though: our documentation isn't very good yet.
