Sounds good to me.
Here's a quick tip I just discovered: After resizing an object, double click on either fill handle to restore the gradient to its default position. You'll lose any custom positioning aspects (like angle or length), but the gradient will match the shape, which sounds like just what you want.
Otherwise, you could submit a feature request to Adobe: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
Ah yes, that's what I need - was hoping it to be automatic and not lose any custom changes but this will suffice since I always keep the handles in the default positions and use color positions instead.
One more thing, I see Photoshop's gradient overlay feature in the Photoshop live effects. However it looks like it is incomplete, as it does not allow any color / positional changes. Is this intentional? Seems like an unfinished feature released...
Yes, Photoshop Live Effects do feel very unfinished... Certain aspects (like Blend mode, for instance) are editable in one effect, but not in another. It's mysterious. However, according to posts elsewhere on this forum, they exist primarily to maintain editability of Layer Styles in Photoshop, so presumably they're serving an important function in that regard.
In the case of a gradient overlay, for instance, it might have been impractical to allow for the editing of gradient stops without porting over a version of Photoshop's Gradient Editor. So it is what it is, for now, I guess.
