Feature summary (what you would like to be able to do and where):
In the translation message editor, I would like to be able to hover over translation variables in order to see the original text that they replace.
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
I need to know the word the the variable replaces when translating to Spanish to know which grammatical gender (el or la) I should add before the translation variable.
Benefits (why should this be implemented?):
Will allow me to translate correctly and not require me to go back to the source page to see what the translation variable originally was, speeding up my translation workflow.
