My first feature request is to add either a child/parent relationship or Categorise Overviews. For example, we have groups of tickets which change status/tags based on the real life status but they all fall under the same Provisioning group. I am not fussed if the parent Overview must also be an overview itself or whether it’s merely a heading.
I’ve created a mockup to explain better hopefully - so in this example, Prov - Activations, Appointments etc would sit under the Provisioning heading. Because we need to have so many overviews, this way is to simply keep the Overview sidebar neat and tidy when opening.
