unclear wether in editor mode or decode mode

[theotheroracle]

the button to switch between modes seems to indicate which mode it's in, but it's much more common convention to have the button say what action clicking it will take, so for example, enter edit mode . i think it would be even clearer if there was a header above the button that says what mode you're in, and have the button just say "decode" or "edit" or maybe even just "switch mode"
