Hi Zabbix devs!

Currently it is possible to filter hostgroups based on the "Problem hosts" widget. However this widget has some flaws:

• ZBXNEXT-9958 Unable to disable subgroup visibility
• ZBXNEXT-9969 Does not work with higher up groups when using subgroups

While these changes to the problem hosts widget would be great, even more logical might be to develop an entirely seperate "Hostgroup navigator". This could give us a cleaner look and feel as well as the customisability required.

The other option is to redevelop "Problem hosts" into a full blown "Hostgroup navigator" by adding features. 

Anyway, sharing some ideas for your consideration. Cheers!
