I for some reason, do not like cabinets. If you have nothing really to hide (visually,etc), and can store everything onto a shelf in decoration mode, then you should be OK. It seems to be more about aesthetics, but that's just me. :)
Ok, I can't seem to expand further - house, front yard, or back yard. I've been in and out of Ur several times and logged in and out of the game. Did you have to do anything special to get more house expansions? Which part were you able to expand? I'd love to have more space, you see. :-)
I had an idea that it would be interesting to "cabinetize" your SDBs, in other words, combine them all into one visual display cabinet or some kind of display case. Instead of just one slot, there could be many and they could hold as much as the regular SDBs hold in each individual slot. of course, I'm not sure how it'd be implemented or anything, but I got the idea when my best friend, upon looking at a screen shot of my house declared I had a nice closet due to how I stacked my SDBs. Regular cabinets are fine for your other goodies, but a display case with cubimals or something? That'd be nifty. Maybe I should post this in the ideas forum... but it's probably already proposed...
