I'm not sure why, but when I first opened your link, I had a view with a wheel. Then I clicked on something I don't remember, and the wheel disappeared and a tree replaced it. But now I can't go back to the wheel, even if I close the tab and reopen your link. Is that a bug?
I'm on Firefox, Android 8.1
Edit : Nevermind, I found the view on the menu, then "Info / Stats / Topology". For information, I never opened the website on a desktop, and the mobile version is a bit overwhelming at first sight. UI animations are rather laggy
Edit2 : Just registered to try to participate to that debate. A bit overwhelming at first, but after understanding the UI, that tool is awesome. Democracy Forum 2.0 right there :-)
Edit3 : I agree that "agree"/"disagree" is easier to understand than "pro"/"cons" when navigating the tree. An action verb makes it more obvious that we can participate, and it then naturally shows a text box to add our arguments. Also, I'm still not a fan of green/red colors.
