Not sure if suggested wrap feature is available for groups and I can't find it in settings/options other than resorting to one handed mode.
When adding apps as a group the displayed app icons should be arranged so that they wrap from the bottom right (or left) rather than from top to bottom. Alternative would be to wrap the container frame window and resize it to fit the number of icons added to the group as when there are only few icons in group it looks empty and takes up screen space unnecessarily.
This will aid in ease of access and one handed use. Especially for groups with only few icons as the current container window takes up the whole screen when opening the group and navigating and selecting desired app usually requires two handed operation in default full screen mode .
