**BUG** Concise problem statement: When switching tabs with the design manager open, it always opens the components folder by default. This behavior is bad design. Steps to reproduce bug: 1. Select the design manager pane. It will open the components folder by default. 2. Close components folder and open nets folder. 3. Switch tab to another schematic or PCB. The components folder is open by default. Switch back to the previous tab. Results: The nets folder is closed and the components folder is open. Expected results: 1) When selecting the design manager initially, no folder should be open by default. This permits the user to choose what folder should be open. The components folder being open by default results in extra work when another folder like nets should be open instead. By all folders closed by default, the user can choose which folder to open in one step without having to close the components folder. 2) When switching tabs to another schematic, the current state of the open design folders should be preserved. If selecting the given schematic/PCB tab for the first time, all design folders should be closed as stated in item 1). When switching back to a previous schematic/PCB tab, the design folder should be opened to what it was already. In other words, the design pane state should be preserved for each schematic/PCB tab. If this is not easily done, then the design pane state should at least stay the same when switching tabs. It should not always open to the components folder.
