The principal idea of Opera Air browser is really interesting and really good, a browser with mindfulness at its core and that focus on a more focused, balanced, and stress-free web is something amazing.
But I think that something that can bust this and make it even more grounbreaker is an option to temporary block or restrict the access to social media. Sometimes the urgence to check social media can be really distracting and stressful, so an option to restrict the access for specific time periods or similars could be really good.
Maybe an option that let us put specific social media sites to restrict, could work with a password to unblock them or some kind of game that can make us re-thing if is necessary or not access to them. Or just a timer. Or an option that let us navigate social media for an specific period of time, and when its over the site is restricted until an hour later or somehting like that.
A rough example could be the extension LeechBlock that does something similar. But something like this integrated directly in the browser following the vision that Opera Air has could be incredible.
Amazing job anyway!
