If the concept is flawed, there will be no execution of the idea. That is what I'm suggesting.
The concepts have nothing to do with the execution. The execution will make reality a a flawed concept, but we can alway fix the code.
But if there is no code to fix, there is nothing to work with.
Write crappy code that demonstrate said concept. Fix said concept if it doesn't work the way people like. Then fix said code. Repeat this process.
Then write correct and clean code. Make it fast. Then, make the interface good.
