From the global facts page (all facts, all hosts) clicking the hostname leads to a search for the host. At best, you have to click the hostname again to get the details page. (At worst, it seems like multiple hosts could come up and there is no way to know which host you initially clicked.)

Clicking hostnames should lead either to the host-specific version of the global page (eg host facts for host 'foo') or to the host summary page.
