I think there is a strange inconsistency in admin UI which I was thinking of reporting to Trac. I want to report here first to see what others thought and if there was a reason for it.
In 'Appearance' you have a tabbed option for 'Mange Themes' and 'Install Themes' and a dividing line.
In all other parent menus you have a small button, e.g. 'Add new page', 'Add new plugin' etc ...
This is inconsistent and I would suggest that all parent menu pages should have a tabbed look with a divider.

As a small additional suggestion, some theme designers write a lot of information about their themes, others write none. This leads to further inconsistency on the page.
I would suggest simplifying the display to just the details; name and version, then 'Activate | Preview | Delete'.
We don't need to know where the template files are located, so add a 4th item, e.g. 'More info' to allow a scroll down or pane showing the rest of the given info.

Big additional suggestion.
Incorporate an 'version compatibility' option on the Theme pages (would mean adding code and tables/scripts to the depository). I would say, "designed for version x.xx' and a 'compatibility check'.
