The left navigation bar tends to get overcrowded. While it is possible to hide topics and to change the sequence, there is no possibility to order them in subcategories. For example “Dashboards”, “System & Development”, “History & Logging”.
It would be good to be able to open and close categories like in a tree view.
It would be good to be able to move (or copy) the categories in “Configuration” and “Development” into these nav bar categories.
(I searched this feature request already exists, but didn’t find something, though I saw in forums that some people would like to have this. If it is already there and I just didn’t see it please point me there.)
