The site design has changed.
What is your opinion? Is it better to change? Or the previous one?

Depends on you. Some like it, some don't. You switch back to v5 if you want.

I like it way better. It's more modernized. Previous one looked old like a windows 7 browser

I think the standards for getting links has changing is probably the bigger issue...even if it is better (not sure, myself), no one likes goalposts moving around...
