From the claap screen
On the top bar, you have two options to move a claap to a different topic: from the dedicated icon or from the settings menu.
When you click on Move to topic, an overlay shows up. You can choose if you want to move the claap to an existing topic or create a new one. If you have too many topics, you can also search them by name in the search box at the top of the overlay.
When you decide to create a new topic, you are redirected to the new topic screen and can give it a name.
From the workspace topic
You can also move claaps directly from the workspace topic. Locate the claap you want to move, hover it to see additional settings, and you see again a dedicated icon and the settings menu. From here, follow the same steps as explained above.
