I do have one observation and it maybe just me. I have no way of clustering a group of connected thoughts, or a way to 'chunk' the concepts. I see some attempt by using coloured lines but there should be a way to make these ideas hierchical and from that be able to zoom up and down various levels of conceptualisation. It would make managing a large network of ideas a lot easier, possibly a bit more ergonomic. Similar to the way the brain works.
It may just be me but was wondering if there's a way to achieve that with the current tooling or if you think there are workarounds?
