Ability to customize the favicon in a design file, prototype, or FigJam file. It could be changed to a logo, color, or first initial to identify which tab is for which workstream more easily. It would also greatly help with the scanability of any pinned tabs, which today the user is only able to see which file it is on hover preview, or knowing the sequential order of your pinned tabs.
Please Figma I beg you 🙏
