Agreed on your point. We need a way to identify those links so that our browser or app can automatically open them through our own instance.
I am thinking along the lines of a registered resource type, or maybe a central redirect page, hosted by each instance, that knows how to send you to your instance to view the post there.
I am sure it is a problem that can be solved. I would however not be in favour of some kind of central identity management. It is to easy a choke point and will take autonomy away from the instances.
Just got Elite Dangerous running today on my fresh Ubuntu. Loaded the modules for the z52 hotas, copied my bindings from my windows instance and there she flies. That makes 3 out o3 for my most played games in Ubuntu.
So far ED is running flawlessly. I need an equivalent for ED market connector though. But that can be manual gor the moment.
