Doesn't install Rated 1 out of 5 stars

This is a cheap-o project with no installer. It just downloads a jar file, and then you have to go searching all over to find out how to install from that.

Fails to show all details of history sidebar Rated 3 out of 5 stars

Yes, it looks good and doesn't waste real estate as so many other themes do (based on a Windows toolbar arrangement). But it doesn't load the "X" that normally appears in the history sidebar for one-click dismissal of the sidebar. It is a small bug that I can get around easily by clicking View > Sidebar > History. Maybe the developer can add that "X" back into the code. ; )

This review is for a previous version of the add-on (1.2.1).
