I had to spend the last few weeks with 3D Max.
It was interesting after having so much time in Blender; I had to get used to the different, less hot-key oriented work-flow. It was easy, because I was able to use my personalized GUI with all the necessary stuff I needed.
Today I came back to Blender and I realized that 2.68 is out; I downloaded and installed it.
It was really cool that I had the opportunity to switch to my previous settings (GUI, hot-keys) immediately; very well done, developers!
On the other hand I had to realize that I forgot at least half of the hot-keys during the last month, what makes me sad and proves the rightness of my formerly guessed suggestions.
