An alternative of Clique for those who use only Plexus. Provides an easy & quick configuration frame.
Choose "Plexus - Click Set“ menu to open the configration frame. It is self-explained.
PS: You can use "##" in a macro, for example, "/cast [target=##]Healing Wave" will be parsed into "/cast [target=raid1]Healing Wave”. The "raid1" is just the raid unit id of each grid button.
