I hope they don't alienate all their windows users who install this and then spend ages looking for their "dock".
If it's a native app then good, but going on a previous comment, it looks like just a frame that loads a webpage that takes up loads of memory so more pain than it's worth.
Tried Trello at the beginning, all my colleagues and I loved it for about 2 days then slowly just began to fall out with it and never used it again. Can't put my finger on what about the app that turned us away... perhaps it's not wanting to do housekeeping which managing your boards feels like in a way. Or the subconscious way it leads you to move all boards to the far right to get them finished, sometimes without having completed the task fully.
We went back to email, phone and chat which seems to work absolutely fine.
