Go directly to issue
Add something like this to app/views/layout/base.rhtml after the "Log in" button:
<% if loggedin? >
<li class="right">Go to bug #<form method="get" action="/issues/show/12">
<input type="text" style="width: 4em" />
< end %>
Except actually working. I don't yet know enough rails to make that form working.
