Interesting concept. I didn't check the tool, but the features look promising. One question, though: How do you ensure seamless user experience when many users are using it at the same time ?
Well, we use decent sockets that we are planning to now upgrade and again, for a MVP, we haven't yet received complaints on this subject. We do have plans to optimise this like Linear has. And that is next in the list of to-dos for our team. :)
