Fillets are removable in v5 using RemoveAndFill (right click the Delete button). Faces resulting from booleans can be moved and rotated. The UI has never been required. Perhaps it's you who hasn't kept up with MoI rather than the other way around.

If what you care about is lots of black, no icons, and ALL CAPS you can do that in MoI. Check out the theme editor for a start. MoI can be customized more thoroughly than any other software I've encountered. I encourage you to transform your version of MoI into the mockup you show in order to gain some appreciation for just how well-designed the stock UI is.

Frankly, your post reads as a crude insult.
