We use Zabbix on 49" displays on the wall, and it would be really nice if we had the following features:

1: dashboard slideshows - just like with regular screen slideshows, prepared dashboards are rotated with a delay

2: map slideshow widget - prepared maps are rotated with a delay

3: problem aware map widget - almost like the map slideshow widget, but you can assign host groups to maps. If there is a problem with an assigned host group, the assigned map will be displayed in the widget. If there are multiple host groups with problems, or multiple maps are assigned to a host group, the relevant maps are rotated with a delay, just like with slideshows. If no problem exists, a default map should be displayed. (extra: besides host groups, IT services could also be assigned to maps. extra 2: could be integrated with item 2: if no host groups are assigned to the maps, the maps are rotated with a delay)

4: adjustable font formatting - characters on a map with a 49" 4K display are unreadable. Browser zoom is a workaround (doesn't even work in dashboard); the fix should be a map/item level font formatting option.
