I’m very much a visual person so I really enjoy using images and emojis throughout my work - I don’t know if it has been mentioned but I think it’s pretty cool. You can add emojis to your board view columns by copying and pasting emojis from https://emojipedia.org/, renaming the column and pasting them in.
Even though Discourse has that built-in, I actually use the Windows emoji picker more often because the search is better. Win+. (period). If you’re on a Mac I don’t know if there is a similar option though.
