Copy & Paste needed

[John]

FireMath is amazing, but the Copy and Paste commands are missing, they are really useful, are you going to add them ?

I have various things in mind, which I would like to add. As soon as I find time I would like to continue adding the possibility to read MathML from disk. Also an Undo feature would be helpful. Copy and paste is challenging. I spent some time thinking about the best way to implement it. So far I did not find an adequate solution.
