Making the Display Titles Collapsable

If there's a populated server, trying to look at different categories of Display Titles can be tricky when only being able to scroll through them. And to be clear, by Display Titles, I mean the title that comes up in the members list above a category of people. For example, the "Online" Display Title comes up for Online Members and vice versa. There's also the role setting to "Display role members separately from online members" allowing custom Display Titles to be made. Like text categories containing text channels, these display titles could be made collapsible for organizational purposes and a better viewing experience.
