I dunno. I prefer the simplistic old design of 7zip. Also:

> In general, NanaZip Sponsor Edition is more like contributor's edition, but we provide a way to buy the honor and make someone look like a source code contributor, because NanaZip is always a community-friendly open-source project.

> If you'd like me to add features or improvements ahead of time, please use paid services.

What?
