A lot of money is spent in design these days, but most of the times nobody cares about the RTL style. In fact, all designs are draw with LTR in mind. Once you have a fairly medium/big app that's designed solely for LTR, the cost of also implementing a RTL rendering is enormous. Every component should be designed twice and implemented with conditional rendering depending on locale.

Isn't there a simpler solution for supporting RTL? Why not render everything LTR and then flip horizontally? Could it work?
