Sadly the new ElementX client is completely unusable missing 80% of the necessary features. The only real progress here (that would call for a 2.0 celebration) is the actually very nice new call system. That only works on element-desktop and elementx however. So no calls are possible with mobile users unless they use the very much not ready for use elementx.
I know this is about the protocol and not the clients, but in the end what matters to users are visible improvements to the UX.
From what i can see they dont seem to have any intentions of improving feature richness of elementx significantly but they are planning on discontinuing the non x version. Im a little confused with their messaging recently.
The protocol supports lots of cool features but if the mobile client will only support a small fraction of those, then whats the point?
