I'm designing a iOS interface that had some last minute changes to the tab bar (across the bottom) and many of the screens had already been set up as Photoshop Layer Comps maintaining visibility, positioning and appearance.
Now that I've made my tweaks to the tab bar I need the new tab bar positioning in all of my existing layer comps. Is there an easy way to accomplish this without having to go through each comp and adjust?
Fastest solution at this point is probably to pick one comp, record an Action that nudges the tab bar to the new location, then use that Action on each of the rest of the comps. Assign a kbsc and it gets quite fast.
[Update: June 2014] All of the problems mentioned in this question are solved in Photoshop CC 2014, which allows Layer Comps within Smart Objects (think "button states") to be selected individually without opening the SO. These selections are included in Layer Styles in the master document.
Synching positions, attributes or visibilities simultaneously across multiple selected Layer Comps is now a feature of the Layer Comps panel.
