It would be nice to manage bookmarks in the app “Weather”. So you can e.g. jump quickly to your hometown.
It is possible to set a bookmark for the weather app. Here are the instructions.
Then you select the “skylark” folder.
Then you choose the folder “Weather”.
If you then select the “data” folder, the weather app will appear.
In the weather app, you select the desired location and other settings.
When everything is ready, you set a bookmark in your browser. So you can jump directly to the weather app with your settings. You need no login.
