Mentimeter should get a function for slide-independent, spontaneous polls without preparation. When you want to do a spontaneous poll in your lecture without prearranged slides, it should be possible to show a single poll-slide with thumb-up, thumb-neutral and thumb-down. And when you close the poll, the results are shown. After that you can return to your regular slides.

And to make it perfect, there should also be a second view, that doesn't show the thumbs, but A, B and C when you want to ask for options, that are not be answered with pro, neutral, contra. So that you tell the voters A is for trip to Zoo, B for trip to themepark and so on. This second quick-poll-type should also allow to choose the number of options up to 10 (A, B, C, D, E, F, G, H, I, J). And it should also have an setting, if the users can choose only one option or multiple of the given options.
