While browsing your feed you can swipe a post to up/downvote it, or reply to it. However if you are within the post itself this does not appear possible and you have to use the buttons. Can this be changed?

Collapsing a post/comment currently only needs a slight touch, and as such I have collapsed posts, or a comment while merely trying to scroll. Can this action be made to require a long touch (or give us the option?)

If either of these are already available within the app would someone point me to the settings as I have been unable to find them.
