Today’s update includes a long-awaited feature, human-readable URLs. This will make navigation and sharing of links much more convenient, spaces can have their own custom URLs, and user profile URLs contain your username.
For spaces, use ‘/s/space-name’ and for users use ‘/u/username’.
The next portion of the update includes options under account settings to create new spaces, view and search the spaces and members directory.
This solves the problem with the lack of sidebar in the mobile app, making it fully-functional from your phone without the need to ever access from another device.
