I think they looked better square rather than round. 
I don’t really control this, the forum service provider just updates their forum software to the latest version every week or two, and it takes on any design changes that have been made part of the Discourse forum software. I agree, this latest change doesn’t seem to be an improvement, but a bit tricky to change without moving host.
I quite like it actually guys…
Not a big deal mate - guess anything takes time to grow on me - defo not worth changing host over that. Thanks for the update though.
