Maybe the only way to find out what people really want and what they need is to ask - I will create a quick anonymous online button survey and try to get enough different moodlers from different countries and different user groups to fill that survey.
Links to that "open survey" should be available within some days (next week?) and results should be visible next week as well. At least a short survey like this might help in creating those additional toolbars, selectors or editor profiles - without need to arrange large user action follow-up studies.
Yet a survey like this may not have any impact on those decisions that Petr and others finally do but we may get some interesting info about user experiences anyway.
