The data store object of extJS is a very nice object, i don't know it 
from other JS libs. It allows to bind to data in general, which can be 
database, xml, array or what ever. It's combined with a reader which 
defines how the data is organized. What i have in mind is  a php class 
which sets the properties for data store. It's an object for often reuse 
whenever datastore is needed. Not deep thought yet.

this is already in core, you have the $this->doc->extJScode which is a 
string that will be wrapped with Ext.onReady(function(){ ... }); in 
doc->startPage.

i really like the vtypes - you have a set of validation rules and use it 
in the objects (forms) for validate like
vtype: email
It's more easy to maintain, easy to extend etc.
Sure, only makes sense if forms use extJS, but a basic set of validation 
rule should be there.

in php. Have a look at http://php-ext.quimera-solutions.com/ where it's 
done completely in php. Nested layouts are not easy to build, so an 
"Autogenerator" would be a great help, but this is just a future vision.

as i brought the "#10144: enable JS-Libs in BE" to core list i would 
like to enable language support there. but this is only for the labels 
coming from extJS, eg the paginator for grids.

The idea here was something that generates the labels dynamic with php 
as inline JS ready to use, like
Ext.lang{
   label.ok = "OK",
   label.cancel = "cancel"
}
