First of all, the recently released "Custom Groups" feature is really useful and helpful to organize entities into groups and order the groups on the home page the way we want.
One feature that I think is really lacking is the ability to manage which items within the group show up first on the list or as an icon. When an item is first added to a custom group there is an option to indicate if it needs to be the first one on the list. But after that point in time there is no way to edit preference on which item should show up first or second or third…and so on.
