On the topic of documentation, I will say only that if I knew the release of version 1.0 was being delayed because documentation was a priority to be written before releasing, and it was going to cost us to wait even one more additional day, I'd much rather hear that 1.0 would be released as early as possible without documentation and released later as a separate download.
Besides, as valid as our friend's comment about documentation was above, we've all had to walk the same learning curve, and though documentation may have helped us along the way, it's definitely not the end all cure for the coding challenges faced daily. The examples have been 20 times more useful to me anyway. Moreover, the extjs documentation rides close enough on the UI side that even our friend above couldn't discount it.
When it comes right down to it, I'd much rather see a company like PACKT Publishing who wrote the Ext JS Cookbooks get onboard with Coolite and fill in the gaps. http://www.packtpub.com/ext-js-3-0-cookbook
I've got deadlines too. I'm 2 months behind, but until 1.0 is released, all deadlines are moot and documentation with the latest rev is lowest priority.
Just my contrarian 2 cents.
