v1.0.14 makes it possible for multiple display entities to be edited at once via other plugins (thanks to @DarkKnights22). A new tools is also added which makes to functionality accessible to normal users.

Group Select Tool
With the help of the group select tool, users can select all unlocked display entities within a given range so that they can all be edited at once. The range of the tool is determined by the current tool precision. If the player shift right clicks with the tool, it will clear the group.
