Well, Figma is on the right track with this one. It would be awesome if somehow marketing team would get the file via browser and then have access to change text layers. Something like that. Now, I put whatever I think it is good and marketing team hardly sees my files because I use Sketch and it is a pure hell to deliver just overview of screens to them. Freeform would be somewhat useful if it worked. The solution has to be simple, a link, no login etc. I have so many tools in my hands right now that I feel sick. Designers need 1-2 tools tops, and now we have a gazillion of useless apps that barely work with each other.
