Ajajj I think you'll need to be more specific about what features you're hoping the iOS/iPad version of Orion could offer, since "different settings also themes" is a bit vague. If you can list some specific examples of flags you'd like that would surely help the Orion team respond to your request.
I also don't understand what "more extension support" being managed under flags would involve; it seems like either Orion would support or not support an extension API or not. I can't see any reason to make the user have to manually change internal Orion settings to enable support for an extension – any extensions Orion has the API support for should Just Work™ when installed, so if you can be more specific about that part of your request too that would help clarify things.
