When assigning a responsibility or role in the "Select Role" popup, there is no easy way to search other than scrolling down what is a rather large list.
It would be good if there was a way to quick search the name of the role that would then filter only those that match the desired search term. This would save a lot of time.
It would also be helpful to have separate icons for a role and responsibility so when searching to tag a role or responsibility it is easily identified as a role or responsibility. One person icon makes sense for a role and the current icon makes sense for a responsibility.
