Would like the ability to choose which features appear in the play bar when publishing. Mostly would like the ability to remove the full screen button, but other customization would be nice, too. Different color schemes, etc.
Related to that would be the ability in the project export options to select whether or not the bookmark TOC window is on by default (users do not intuitively know to roll over the index icon in the toolbar)
I was just trying to figure out how to do this . . . . I agree that this would be great. There do seem to be a lot of issues relating to the full-screen button and how it functions inside an LMS. Being able to eliminate it all together would be a good thing.
