Filtering the status page is very easy. There are three properties that can be used as filter: system, status and tool. To set the filter just click on the tables headline.
The default filter shows all systems and tools but no successful checks. When working with Leankoala this turns out to be the way people are using the status pages. Filters are stored within the browser. That means that the next time you open the project on the same machine the filters are restored. If you chance the computer you have to reset the filter.
