It's been a few weeks since you had the option of moving the project inspector on the left of the workspace. We are considering if we should make that the default arrangement, or we should keep the inspector where it is to leave more space for the toolbox.

p.s.: asking for dockable panels is not an option at the moment, but we're aware they exist.
