In the tables, users are able to customize the size of columns and which columns they view. However, when users navigate away from the page or log out of the system, those changes are lost and they must reformat their tables. Please make it so they do not have to re-enter their customizations every time they see a table.
Does EXTJS 3.2.2 support saving customizations grid?
Already available. Check out the "stateful" config on grid panels
Having said that - if you're going to be retaining state on a high number of ext panels, then I would recommend using an "http state provider", as some browsers have a limit of the number of cookies one domain can store, which will cause issues if exceeded (I found this out the hard way ): http://www.sencha.com/forum/showthre...State-Provider
