Editing a tag is as follows: Swipe the desired tag to the left, as shown in the picture below.
Once the tag has been swiped 3 buttons are displayed:
- The button on the left allows you to specify a color to the tag.
- The button in the middle with the pencil icon allows you to edit the name of the tag.
- That trash button on the right deletes the tag.
When specifying a color a pop-up menu is displayed, as shown in the picture below, and the desired color can be selected.
