As with Mission Control, switching to an app switches you to the workspace containing that app’s window(s). If an app has windows in multiple workspaces, each time you click that app’s icon in the Dock, you cycle between those workspaces.

ReSpaceApp is still in the beta stage, so it’s still got some quirks. For example, while ReSpaceApp arranges your workspaces in a grid, these are still Mission Control desktops under the hood—if you enter Mission Control, you’ll see them arranged linearly. Which means that on a laptop, or if you’re using a Magic Trackpad, you can use a multi-finger swipe to the left or right to switch between those workspaces, but not up or down. This can quickly get confusing.

Another issue is that if you enable ReSpaceApp’s Circulation feature—which allows the aforementioned capability to drag a window against the edge of the screen and circulate through workspaces—full-screen apps aren’t navigable using ReSpaceApp’s shortcuts. But if you disable Circulation, which then allows you to access full-screen apps by going past the right-most workspace as you would in Mission Control, you can no longer easily move a window to a workspace at a different vertical level. The developer has indicated that improvements to full-screen-mode compatibility are in the works.

There are also a few minor issue. For example, the program’s preferences window frustratingly disappears whenever you click away from it. And while making a workspace grid prompts you with an Add More button to create the additional workspaces, moving to a grid (one with fewer workspaces) alerts you than you currently have more, but doesn’t provide you with a way to delete the extras.

I’m looking forward to updates to ReSpaceApp. I’m still a fan of Spaces, and I’ve been disappointed in Mission Control’s approach to multiple workspaces. With some improvements, ReSpaceApp could deliver the best of both Spaces and Mission Control.
