Trello: focus mode on a single list
Dims every list and brightens only the one you click, so you focus on one stage.
Code to copy
// Focus mode: dim every list except the one you click
(function () {
const ID = 'jz-trl-focus';
if (document.getElementById(ID)) { document.getElementById(ID).remove(); }
const st = document.createElement('style');
st.id = ID;
st.textContent = '.list-wrapper,[data-testid="list-wrapper"]{opacity:.35;transition:opacity .15s}.jz-focus-list{opacity:1!important}';
document.head.appendChild(st);
document.addEventListener('click', function (e) {
const list = e.target.closest('[data-testid="list-wrapper"], .list-wrapper');
document.querySelectorAll('.jz-focus-list').forEach(function (n) { n.classList.remove('jz-focus-list'); });
if (list) { list.classList.add('jz-focus-list'); }
}, true);
