I'm a little disappointed to see that the roadmap makes no mention of an improved grid. As we all know, the current Grid implementation falls flat on its face with more than several hundred records, due to the fact that it is using a table for each row. I know that Animal has created an alternative single table grid. But, I really think this should be a core offering in ExtJs to be more competitive.
So my question for the ExtJs team, have you decided to just let this be a third party fix, or do you ever plan on taking a serious look at improving the performance of the grid? After all, the purpose of a grid is to show data and as we all know, this world is producing more and more data, not less. So a grid is expected to be able to easily handle hundreds, if not thousands of items. I see that there is a TreeGrid planned for the next release, which is WAY cool and something we can very much use. I just hope the performance is up to par.
