Agree that the fixed width is a HORRIBLE backwards step. And, it makes the website unusable on a narrow screen like the iPhone Safari browser - scroll doesn't work on GC.com.
Agree that a lot of things that previously worked really well were "fixed" and are now worse than before.
Readability has gone DOWN - fonts are smaller, colours are less distinct, watermark background is crazily bad style.
There were lots of things that could have been improved - that is, things that LOTS of users had been asking for, but it appears there were not looked at. Groundspeak needs to keep (start?) listening to their customers - it's us who pay you, remember!
Beta maps are not up to scratch (ok, they're still beta, but they are now the default map page).
That's my two pennyworth - overall rather disappointed with the output from a commercial, supposedly professional, organisation.
