Is it Possible to Reorder the List of Spaces?

Yes, inside a group of spaces. Groups are available on the "Corporate" and "Enterprise" plans.

1. In the menu on the left, hover over the group and click its three dots.

2. Click "Reorder Spaces".

3. Drag the spaces to change their order.

Without groups, spaces are listed in alphabetical order. To change this order, you can start the names of the spaces with a number.
