The integration with Google Sheets, Slack & Trello are great features that I like! Sometimes it's hard to create new cards when you don't have access in your team room or shared drive but they're working towards improving this functionality so hopefully we can get there soon? Try out kanboards trial for at least 2 weeks- 3 if possible before deciding whether its right fit/suitable enough (it took me about two months).
It helps us keep track of our tasks using different tools such as slack chats etc., which makes them more visible across all channels used by my teams within office space.
