Sometimes I end up working on files that I've imported from a PSD. Often they have a lot of layers (could be 100+ due to the way Photoshop works and/or the artist I'm working with structures her files...), and it's pretty tedious to tick/untick all the layers one by one when I want to view just a single layer, or turn them all back on again to view the resulting image, etc.
Unless I've missed something there's no way to 'batch' hide/show layers? A right click option on the layers list for hide/show all would work: if you could shift-select a range of layers to hide/show that would be even better, although not quite so important.
Cheers!
