"Hv3 opens on a gun metal gray window with four top-level menus,
a toolbar consisting of five basic navigation choices, and the URL
entry field (as well as debugging tools that are, presumably,
temporary). At the bottom is a status bar that gives instructions
for toggling between modes, but [H3v screenshot] apparently does
nothing yet. Both bookmarks and downloads open in separate tabs,
rather than in a menu or a floating window, which makes for a less
cluttered appearance than in most browsers, but does result in each
new tab opening by displaying bookmarks. This default occasionally
comes in handy, but is more often an annoying preliminary step to
what you really want to do.
"Two unusual features in the Hv3 window are the ability to hide
the menus and toolbar to maximize display space, and a tree view of
the page's HTML source. Both are available from the right-click
menu for a link. The tree view is especially welcome, since it is
quicker to navigate than the plain text file of markup you get in
most browsers. The difference, I suspect, is that the Hv3 assumes
that users are actively interested in looking through the markup
and using it as efficiently as possible, so that the view is not
just an after-thought."
