Questions about the webpage created by hobbit

Hi all,

I was just wandering around at the website of my hobbit installation and wanted to know, if there is a way to increase the time and events user-801b0d835d7c@xymon.invalid (... events received in the last ... minutes).
I didn't find a variable to set in the scripts.
And maybe there is also a trick not to have 2 columns displayed but only 1.

Thanks in advance
Torsten
