Enable more than one method to be open at a time in MS and LC Method Areas

Problem: a user may want to be able to build a new MS or LC method based closely on an older/different one. Current Situation: a user needs to open an old method, take a screenshot of the method and then open another method to compare the two. Ideal Situation: a user would be able to open two or more methods and switch between them - comparing side-by-side. It is true that you could use SAVE AS but as you are modifying a gradient (especially a more complex one), having the original on the side would help.
