So honestly I hate the comment swiping interface, I know what you're talking about though. I'll put it on the list for an option but it's going to be low since I find it to be bad UX - to me, swiping should be to change something on your screen.

The swiping between posts sounds like a great idea though, that'll almost definitely be in the next version

And sorting? Custom sorts and feeds are like my main design goal, that'll definitely be in there

The other thing is saving your place - that was my biggest complaint personally. You can already click on anything to see more about it and go back without losing your place

You can even change accounts or sorting methods and go back to where you were - I'm playing with making that more intuitive though, I disabled it for the current version because it was awkward

I'll save your post and ping you for the next big update
