Sorry, I didn’t see this reply until now. I mean the button for whatever the post is linking to. Pictures, other communities, or external links. I’m right handed and the button is on the left. This makes it a big reach for my thumb to reach across my screen and I’m less likely to click on things or use your app because of it. I know it’s a small complaint but it’s all about feel, especially when it comes to apps, that’s why reddit had so many!
