I started using extjs in the tail end of the Jack Slocum period. He was a formidable one man army who delivered what I considered an elegant but incomplete vision. I feel that after he dropped out of it they never managed to reach the same level of clarity in building out the missing pieces. Each release brought more features but also more cognitive load, and it made it harder to learn. Eventually, with v4, they just built a new framework with a different philosophy that they then branded as extjs. I wonder how extjs would have turned out had jack been there all along.
