Great performance boost.
Also:
* Input field to copy @username
Once we can post, this may be handy
* Search is also an iframe (containing an iframe per user)
So you can keep composing a twist while searching for usernames
* Should be responsive for cellulars (I can only resize browser
to check. Got no phone. Anyway, the floating "Fork me" footer
now has a link to navigation (local users), and that's about all
the essential navigation. You can scroll a bit down from there
for search results, or all the way up for the content.
* Make sure Dillo etc. that don't see bootstrap font icon
can still have text links to everything
Enjoy
