Jerome (ID: 000000257f691dca) Voted 1 ★ - Updated 10/01/2024 My updated review (October 2024): 1 star Unfortunately Trello has killed this extension, included the collapsible list feature... as a premium feature. So you have to pay Trello to do this basic action. Discusted. Thanks to the developer for this hack which worked... until now. :( My previous review April 2023): 5 stars Should be a native Trello feature, but THANK YOU so much for creating that extension, which works like a breeze!
