Build Mode Feedback for EA

I'm not being rude, it's a really, really long post so I didn't read in whole, skipped few parts. I agree on many things, such as smaller fences, different wall heights on the same level/storey, skylights, flat roofs, multiple windows on same square wall, increase the number of levels and manual wall edges. One thing I'd like to add are circular, hexagonal and hectagonal roofs. Also, ability to extend or shorten the trims on every roof kind, including every edge. For example, the gabled roof can extend the trims only on the lower trims, while the side trims can't be extended. Hipped roof looks really weird as it's floating.
