Hi, Pancenter -
#1. The 'set as default' function is not a global setting for tab choices; it applies only to the specific community in which it was chosen, as well as to one's homepage.
#2. Not sure what you're not seeing. The info presented is in a different array, and some is indeed different than what was presented in AD. Since ASC is a new construction, rather than a remod of AD, more specific details would help those resonsible for it to know what features/info are desirable.
#3. After signing in on the sign in page, I'm taken to the last page I looked at in ASC. Typically this is the homepage, since I have that set as my start page for ASC - initially the generic 'welcome stranger' view, then after sign-in to my personalized version of it.
#4. Some folk with bad eyesight and/or small devices (iPhones, iPads, etc.) find the large fonts convenient; others don't. The balloons are a bit cutsey. Some of us have asked for some remedies re better use of available whitespace; we'll have to wait to see if any of those are acted upon.

Re editing - unlike all other posts in a discussion (thread), the edit function for the original (thread-starting) post is in the Actions box in the RH sidebar.
