Also if you are writing a response and scroll up or leave the page to check another thread etc if you tap or click on the orange response title it takes you back to the position of the post you’re commenting on
I mean if you start typing a message you can navigate to anywhere on the forum website without closing the comment box and to get back to where you were when commenting just hit the orange text at the top of the comment box. Quite useful if you want to search the forum to add a cross reference into a response.
