A simple, clean theme for Roam Research: https://www.reddit.com/r/RoamResearch/comments/gmkdxe/a_simple_cleaner_theme_for_roam/
Use a tool like User JS and CSS to inject this JS if you want to fix the sidebar:
function addToggleClassToSidebar () {
var rightSidebar = document.querySelector('#roam-right-sidebar-content');
var rightSidebarContainer = document.querySelector('#right-sidebar');
if( rightSidebarContainer === null )
return;
if( rightSidebar === null || rightSidebar.innerText === "" )
rightSidebarContainer.classList.remove('sidebarOpen')
else
rightSidebarContainer.classList.add('sidebarOpen')
}
document.addEventListener('DOMContentLoaded', function () {
window.setInterval(addToggleClassToSidebar, 1000);
});
