A simple blender add-on for facilitating the use of the blender addon GIMI this add-on adds five menus to vertex group context menu/special menu
1. Merge shared name VGs
looks at the active selected VG (y) then merges all y.xxx VGs to y; then it sorts the VGs
2. Merge shared name VGs with the active VG
searches ALL VGs (y) and merges all y.xxx VGs to y; then it sorts the VGs
3. Fill VGs
finds the lowest numbered existing VG and the highest one, then fills all the space between them so no number would be missing between the lowest and highest; then it sorts the VGs
4. Remove unused VGs
looks at all the VGs finds the one that have no verts added and weighetd to them, then removes them
