Highlights todo, doing and done lists.
To do lists stay as they are. Doing lists are highlighted. Done lists are faded and greyed out.
If there's a todo or doing list on the board, all other lists are dimmed. List Highlighter works automatically with the title of your list, or with hashtags.
Just name your list Todo, Doing, or Done, and styles will be applied automatically. Or name it what you like and tag it with a hashtag (e.g. #todo, #doing, #done). The hashtag will only appear when you're editing the title.
VERSION 3.0 -- 16 August 2017
Version 3 allows you to choose your own highlight colour, gives you the ability to split up long lists with header and separator cards, adds a toolbar button to toggle highlighting on particular Trello pages, as well as a couple of fine tuning controls. Enjoy! And let me know what you think.
