Why user have got that ugly flat design style? Is awful. Older menu design was really great.
I hate flat design and I don't use it. I don't understand popularity in last years (flat logo Windows, flat menu Windows etc).
It is very bad. Can we change it to previous?
No, it can't be changed. The rest is not worth discussing. There are endless threads on how wrong Adobe got it everywhere on the Internet.
But at least sombody know why they do that? It is awful now.
