I like the current implementation as an idea, but I really miss icons. Emoticons are so busy and inconsistent, it makes everything look very messy. I would love having either my own icon set, or at least one Tana set that has a single color and is more calm. Notion icons are a pretty good example, in my opinion.
Or even better, a tana set that changes color according to supertag's color, but maybe that's too much effort
