Suggestion: Change new preview buttons in camera raw to BYPASS buttons

The disadvantage of having a preview button that you can not keep toggled off, is that you have to reset your adjustments if you want to get rid of said adjustments. This means that if you made adjustments that you might like to refer back to at a later date, you would have to remember where your sliders were. A bypass button that allows you to keep your adjustments while turning that section off is more practical. 

Perhaps even offering the option of both a bypass/preview button would be even better.
