We run a lot of schedules on our FME Server and to troubleshoot some of the jobs, we'd sometimes have to inspect several logs at a time.
Currently in the Jobs > Completed view, it is only possible to open a log within the same window or tab. It is essentially limited to viewing one log at a time, unless you download the log and open it in a text editor or do similar workarounds.
Switching between the (filtered) list and log with browser back/forward takes some time due to dynamic reloading of the list, and some filters don't always persist when going back and forth.
It would be great if logs could be opened in new tabs via middle click like normal links.
