More changes in group management are available for merging. It adds, in my op, useful functionality, but you indicated you wanted to stabilize, so lets discuss. In case you don't want it now, though, but do later, then it'll be up to you to resolve arisen merge conflicts.
Most notable function changes:
* A subset of the original group can be target for items transfer and equip. The character names are clickable to include/exclude it as a target.
* It is possible to click an item, owned by a part of the group, to select all members of the group that own this item.
* Similarly items equipped by a part of the group can be clicked to select the members that have it equipped.
* If there are alternate items, for other members, for this equipment slot, then clicking the slot again will select those members with this next item equipped.
* There's an select all persons button.
Explanation is less intuitive than just trying it.
