I use MN on my phone but through a chrome browser.
If I got to "I'm on" it shows me threads I've posted on with an arrow to go to any particular post placed on the right hand side of the post!. Before, you could just click anywhere on the post to go to it. Now you have to click on the rh arrow! This is really counterintuitive for left handers and a pain as your hand has to cross the screen to do it blocking your view.
Why was this thought to be better than clicking anywhere on the post where left handers could ergonomically just click the LHS of it?
