When users exist, Trndi will ask which one you want to use on start-up:

Click Save, before closing the window or selecting another user. Settings wont apply unless you click Save!
The color chosen will be assigned to the window when Trndi loads the user. The username is also displayed in the title bar. If you are on Windows, the titlebar will change colors, while on Linux/macOS a sidebar will appear.
There is always a standard user, you can assign it a nickname and color aswell. The standard user is the information you’ve saved before adding additional users. It cannot be removed.
If you add a username again, which has been deleted before, the setting will still be saved. Thus, deleting a user removes them from the list, but does not delete their data!
