errr, that's the point, it's basic and simple, it doesn't support the same feature set, but, in many cases, you can get away without all the features.....

like when you can make powerpoints without ever needing to draw, in fact, not having drawing tools means you keep your things simpler and don't over complicate the essential thing you are doing.

it certainly won't suit everyone though, and for me, I went Jira -> Trello -> Youtrack and got a nice blend of things.
