Hidden columns should not be showed one moment in time. Start up toaster. All builds-> core-image-sato qemux86->packages Only default columns are showed. Click a page button(such as 6) to enter another page of package link. A splash screen occurs and all columns(hidden and unhidden columns) are showed. Acutally hidden columns should not be showed. A second later，only default columns are showed.

Hi Yuan, This is not a bug, but related to the way we have implemented the "edit columns" menu: instead of hiding all columns by default, then show the ones selected in the "Edit columns" menu, we show all columns by default, then hide the ones not selected in the "Edit columns" menu. This makes sure the interface does not fall apart if javacript is not (well) supported by the client. I've also been told that a short animation was added to the column hiding/showing to avoid a flickering effect on the screen. Both things together account for the effect you see.
Well. I would close the bug. But I think we need imporve the user experience.
