True, i kinda only ordered it to support mobile Linux development, however, by now I think there would have been much better places to do this than this company.

As someone who requested a refund, I can confirm to have neither the phone nor the refund :(

Under advanced you can enable swipe to change language. Then you can swipe up from space to cycle through your languages. I find it quick enough. No idea about gifs but holding return you can insert emojis.

Same for me

depending on what you do there are large benefits, for me they are executable code blocks (i.e. jupyter like experience) and way better latex support (if you type equations that are more involved this is rather important).
