[TYPO3-mvc] mvc_extjs patch and something to give back

[Dmitri Pisarev]

Hello dear list!
I was in need to create a basic ExtJs library module for our new 
website. I use tt_news for backend storage, because it has very cool 
NewsAdmin, which allows extensive use of categories.
Everything went really smoothly, and now my extension works, displaying 
ExtJS GridPanel of tt_news, with filtering by categories and with remote 
ordering and paging.

I have two questions:
1) I was using new viewHelpers from mvc_extjs extensively, but they are 
not very ready, so I had to patch it locally (many properties missing, 
some are miss-implemented, like autoLoad accepts not only bool, but 
config object as well, etc.). What shall I do, propose a patch to 
mvc_extjs, or extend those viewHelpers in my extension?

2) I really appreciate the help I receive in this lists, but feel 
ashamed I do give nothing back, because I'm really just a newbie at 
extbase. I have noticed a lack of extbase demo extensions, may be my 
library extension could be of a help to someone? It's not 100% polished, 
and I actually have a few questions how to polish it, but as a demo it 
will work. What do you think?

Thanks for your support!
Dmitri.
