First link active in the navigation

Hello, 

When I load a Mendix application (for example this one), in the sidebar, the first link should have a "active" class. So the user will know where he is.

The same kind of problem appears when I click on the logo (MX in the previous example): I go to the homepage but the sidebar fist link should be also activated.

Could you fix that please?

Cheers

(it is better with an "active" class)
