All the things you listed will definitely change- especially the bit about layouts. But don't worry, it will be much more user friendly and look nicer.
Feels like the two weeks is almost up, doesn't it? How long has two weeks taken? A few years? Dujo must be living in Narnia... Time is quite nutty there, you know.
v. i was joking. it's something from the mibba merch store, xD
After all, Dujo is a space alien using Croatia as a cover for his human-ness. So, clearly, his judgement of time is warped and two weeks actually equals about three and a half years :3
Dujo said it will be coming soon. And from what I've seen of all his updates, most of them are pretty good. I doubt he would change Mibba to where we wouldn't like it, and I doubt everything will change. I'm excited, though. :3
I'm actually looking forward to the new mibba, but I wouldn't worry about it too much. Dujo has been promising us a new mibba since last year, probably longer.
