I've been in SL for 3 years, and I've learned to wait and see about improvements. It seems any time there are major changes some of my stuff is ruined, so you learn to develop a bit of a thick skin towards being optimistic.
Right now, literally, I just opened an object that had 4 items in it, and only 1 has appeared in the folder it created. Perhaps the other 3 will appear, perhaps not. The problems recently with the Inventory have been impressive, and sadly it seems that they are getting worse, not better. When I glance at my Friends list and see that many of the offline names have 2 entries for the same person, I smile in amusement. There have been some noticable improvements, and Viewer 2 did impliment some good ideas that I do applaud. It only took a year or so to fix the edit window anchoring problem with the sub windows color and texture edit windows. And finally making TPs more web like, with the ability to click a back arrow ... well done sirs.
I had hoped LL would address the limited and deeply flawed Search software in SL, but that seems to be a very low priority. Even with adult clearance, once I do an initial search, should I use that window to do another, I can only access General info. Sometimes I truly wonder how often those who make these decisions actually Use SL. This "back to basics" of working on User Needs, not Designer Greeds should ALWAYS be the focus.
