One of the things that would be impacted by this would be logic that appends a variable value to an animation name... for example if I have 5 different jump animations (jumpWall, jumpDouble, jumpSuper, etc....) I may have different events that set my jumptype variable to Wall, Double or Super, I can then call Set Animation and set it to = "jump" + jumptype to get it to pick the correct animation for me. This is a common scenario for more complicated games that need context sensitive operations. So if the dropdown list (which I have also asked for in the past) were to be added it would need to still allow for us to enter our own data as well instead of forcing us to use the individual animation names.
