Customize the look of your Trello boards by enabling card background colors (taken from labels) and header cards.
You can try out this extension on the example board
To display headers, add -- at the start and end of the text for your card.
If this card has a label, then the color of the first label will be used as the color for the header text
If this card has a label, then the background color will be based on the color of the first label. If you only have one label, then that label will be hidden, otherwise you'll still be able to see all the labels displayed.
Other:
- Introduce global settings
- Introduce per-board settings
- Activate content script sooner (rather than when idle) so that styles can be applied as soon as cards are displayed.
