I have some use case where I have Items that absolutely must be in "Normal" state but can have a value of zero.

When assigning a large number of similarly named Items to a widget, we can use a wildcard to simplify the task, however then we cannot filter out Items with a 0 value.

It could be useful to have an option to filter out Items with a 0 value. I'm thinking of widgets like the Item Browser, Graph and Pie Chart widgets, but it may be useful in more widget types.
