Right, I did evaluate that as I worked on the button styling. But there’s nothing I was able to draw from it in creating the share button. The fonts are generic, the resolution is low and pixelated, the drop shadows and embossing are kinda dated, the eagle and flag are too complex.
I’m not criticizing it. I’m just thinking it could use an update.
That's legit. As to a tab logo or share button, a simple five-point star on the red and blue background with FR on top would definitely suffice.
