As a suggestion.
It would be great to have the ability to configure the column widths. I find it hard to read when there’s a lot of content with titles that go over 2 lines.
For example, this console script I threw together I feel makes my boards a lot easier to read
$(document.head).append('<style>.project-board-container .card { max-width: 460px !important } .project-board-container .releases .release { width: 460px !important} .project-board-container .releases-footers .release, .project-board-container .releases-headers .release, .project-board-container .releases .release { width: 460px !important} </style>');
