Can we do that ?
For instance the status column is only useful when at least one file in the lister has a label. But it could be useful in any case.
Closest you can do is set them to autosize so they don't take up much space when there's nothing in them.
Can we hide them from script? i have a DetailedEnhanced folder format that i mostly use with columns for dimensions, bit rate etc. When im in folders that doesnt have these data i dont want them displayed, but if they have, the collapse option just hides them if there isnt space.
