We’re thinking about implementing this feature in the future.
However we would need your feedback so we can see whether we can implement it to properly satisfy your needs. Could you please comment the specific use case for layer comps in your workflow and how exactly are you using them?
Are you using layer comps only for showing and hiding of layers – effectively creating different states of the design?
Or are you also using them for changing styles and effects of specific layers?
Your input will help us figure out the best way to support layer comps if we are able to. If you have any example design which you could send us so we can understand how you use layer comps, please send it to email@example.com
