Well, I wasn't aware of, at least, some of those tools. But, also... Contextualise really fits my very specific needs and way of modeling knowledge/information. So, I was scratching a very specific itch. But, also I hope that with Contextualise I am putting something new on the table even if that is just a somewhat simple UI on top of a straight-forward but understandable data model.

Thanks for your feedback. Genuinely appreciated.
