To add a new favourite please tap the magnifying glass in the upper right corner. Type in the name of the location you are looking for. Often it automatically displays a list of suggestions, after the first 4-5 entered letters. If the desired location is not listed, please write the exact name of the location in the search field and then tap on the "Search" key on the keyboard.
Press the “+” button next to the search result to save it as a favourite.
To delete a favourite just open the favourite list, tap the pencil in the upper right and then simply tap the "x" button next to the location. Here you can also easily rearrange by dragging and dropping.
