Power conversion

Gyuri 0

It is very easy to mess up power conversion in the game due to 2 reasons.

The abbreviations (o,q,k,c,pw) are not friendly to new players, and they can easily mess up things, especially if their native language is not english. Also, the new look almost completely removed these abbreviations.
The position of power conversion options change as you spend power, so for example if you have 3 pw and convert 1pw to 1c the 3pw->o conversion will disappear, and the remaining options rearrange themselves.

I suggest that instead of abbreviations, we could use the symbols. So instead of the button that tells me convert 1o to 1c we could have a button that tells me [<ore icon> <rightarrow> <coin icon>]. Also we could grey out the non-available options instead of make them disappear.

Thanks!
