This is really neat. Found it to be pretty intuitive, and selecting multiple nodes is super useful. I noticed the arrow links on the top of the node open on the same window, which I would have expected to open on a blank window so that I don't lose the current view.
the links open in the same page because navigating away from kinopio.club doesn't result in any data loss.
Because there are usability issues with new tab/window spawning for less pro computer users, the w3c recommendation is that you should only use target=_blank links when moving to a new page would destroy your page state (e.g. if you were filling out a form).
(Just in case you haven't tried it yet, middle mouse clicks will open the url in a new window/tab)
