I actually like it, apart from maybe text needing a little bit more padding when close to the edges of the cards etc.
The UI is minimalist without feeling like it's lacking, it's usable and the performance is great because it doesn't try to have lots of fancy gradients or animations for the sake of it.
Still using OpenProject because of the nice multi-project feature set there and Jira having rotten my brain, but Kanboard is easily 10x times faster than the sluggish OpenProject experience.
