Used to be a lot of useful things in that panel.
They took them out and made you have a keybind for them.
So now if you don’t use something all the time and haven’t memorised it, you can’t do anything about it.
3.3 is keybindings hell.
Complete and utter rubbish. ^^^ Beacon is still there under the new "Ship" Panel, as is everything else I can remember.
Nothing missing as far as I can tell. (and if there is something missing, raise a Bug report)
As for key bindings, seriously - there are about 2-3 new essential bindings that are needed from within normal flight cockpit mode. toggle Analysis mode & enter FSS, toggle Night Vision (bind optional). Yes that can require some creative thinking if you already have custom bindings. And if you already have custom bindings then I'm sure you can manage it.
But all the other bindings can reuse the same controls you'd normally use within the cockpit for flight etc... Much like the galaxy map, they don't conflict. Granted it's tougher on console (i'm on Xbox and PC), and tougher still if on a normal console Controller.
