They've fixed a few annoyances in Anaconda in F19 Alpha including actually offering MATE as a desktop option (F18 never showed it in Anaconda - you had to know to groupinstall it later on). Still no package version numbers or install time remaining when the packages are being installed though - both blatantly obvious requirements!
The Anaconda interface is still LUDICROUSLY SHOUTY (yes, much of it is fully capitalised and even adds bolding on top of that!) and the custom disk partitioning still needs further work. It has a nasty mixture of size units (yes, it's possible to see K, MB and GB all on the same screen) and the option - if it exists - to "use all remaining space on device" when creating a new partition (which you're surely almost always going to need?) didn't jump out at me.
