What about a feature that allows you to mark events in the Heatmap addon? It would be pretty simple I reckon, you click a "square" day, choose "add title" and type in like "Neurology exam" and then choose a color. Then that day would be marked with that color instead of the grey color (if it's in the future that is), and when hovering the mouse above it, it would say "Neurology exam" above the "205 cards due". Anyone else think this would be awesome?
