With the extensive usage of Confluence, an issue we faced is the long list of spaces on the dashboard.
Beside a longer loading time, the long list also affects the layout of the dashboard. It is also more difficult to search for spaces.
Luckily, with the SpeakEasy extension, it is very easy to change the look and feel. We tried and developed the Akeles Space Lister Extension.
