Its really nice - one of the better Trello clones. I just wish Trello development would restart - it seems to have got really slow in the last 6 months with no new major features etc.
The fact that it's relatively light on features is one of the things that makes Trello great.
They've been working on the Apple Watch app, other than that I think Trello is pretty feature complete. What other features do you think they need to add?
One deal-breaker for me at least is the lack of id numbers on the cards. It's much easier to tell someone, hey I completed card #8 than "Really long description of task". I know there is a bookmarklet out there that surfaces the hidden numbers, but getting an entire team of non-technical people to run it consistently is near impossible. It really should just be a configuration option.
Also I've been requesting a simple list item count for at least a year. As in, show me that a certain board has X number of cards in it. Pretty basic stuff that is still missing despite paying for the service and asking for it multiple times.
