The new narrow popup window used to compose a post makes it more difficult to see similar posts than previously. Now the “your topic is similar to” pane overlaps your current text box instead of flowing to the right.
Additionally, on mobile forums, when replying to other threads, the pane takes up the whole screen and is oftentimes unresponsive if you want to temporarily cascade the response pane to access the previous thread content and forces you to reload.
I also have to tap the “create topic” or reply button multiple times on mobile. Sometimes after multiple attempts of the button being completely unusable, I yet again have to refresh the page, which forces it to send what I was composing to the current drafts and I have to pull it back up from there.
