Why not let Mesh Layer be edited on Frame 0

[Panha]

I know that on frame 0, we design. However, when it comes to Mesh layers to control other layers, we need to go to other frame rather than frame 0, most of the time I go to frame 1, to design. Then I come up with an idea for a feature request. Why not let Mesh Layer be edited on Frame 0 (with the effect to the mesh be seen) by giving one more option (quick button or right click option on the layer) for users to quickly switch the mesh (temporarily) back and forth to normal layer and mesh layer?
