Grouping Mod [UPDATE]

The mod allows you to put items in selection groups so if one of the items is selected, all of the them in the group get selected too. You can make multiple groups. If you ungroup everything before saving it (to upload it to workshop), for others the contraption won't require downloading this mod

Now you can select objects individually without ungrouping them!
-Hold SHIFT to select individual objects
-To select multiple groups - select one group and then select other one while holding SHIFT

Ungroup your whole contraption before publishing it in steam workshop!

Select objects, click right mouse button, name your group
