Column Highlight: Add color bars to work stages
Looking to improve your board readability?
The Column Highlight power-up lets you underline the board’s columns with colorful strips, making it easier to identify specific process stages.
Enable the feature on your board’s Settings → Power-Ups page and choose whether to highlight just one column or all of them, depending on your needs.

Want to color an entire column or swimlane area instead?
That too is possible, provided that you’re happy to customize the Column Background script to match your column and swimlane names.
