Ian A lot of Orion users come from Safari and prefer the way full screen is handled which is like in Safari. That puts us in an awkward position as even if we had the resources to commit to changing this (which is at webkit level) there would be a group of users that will be unsatisfied - unless we added an option in settings, but if this is an option they you can imagine settings having thousands of options like this.
So we chose to follow the standard set by Safari, which is the reference browser by the manufacturer of the OS we are all using, but also a solution that WebKit ships with.
This is not to say that this will never happen, but just to manage expectations.
