Hi David, thanks for reaching out.

We do support the features you described in the “Layers” panel, which can be accessed from the right sidebar menu.

By the way, we also have a left panel with a hierarchy of projects and boards to help with navigation. You can open it by clicking the “Show project list” icon at the top left. (see video guide https://youtu.be/WR3EH8FqQjg)

Kindly see attached screenshot and video for the 2 mentioned panels.

Hope this helps.
