As a group owner, adding new members to my team with the new developer hub is really difficult due to the lack of a search bar.
Of course, this is not a problem for small groups, but I add people in my main group with over 100 members. And for groups with thousands+ members? Forget it.
I most commonly add people who just joined the group, which are, for some reason, displayed at the very bottom of the last page, when I think they should be at the very top of the first page. Or, add some type of filter along with a search bar so that we can search for individuals who might not necessarily be the newest member. This would make adding people to my Team way less of a headache and, for other groups with less opportunity, would remove the requirement to make a second dev-only group.
