Icon state for @ifset

Hi,

There is a button:
@ifset:VIEW=details
Set COLUMNSADD=sizerel(2)
GetSizes

Currently in a mode different than details, the button appears normal, and in details mode it appears pressed.
More natural it would be if it appeared inactive in a mode different than details and normal in details mode.

Maybe some modifier for ifset to determine what look the button should have?

Put @toggle:invert at the top to reverse when it appears pressed, or @toggle:disable to prevent it being pressed at all.

@toggle:invert
@ifset:VIEW=details
Set COLUMNSADD=sizerel(2)
GetSizes
