The 'Units' panel provides the possibility to create (including creation
from WLP), view, edit, copy, and delete units, export/import their
properties and send SMS messages to them.
To work with units, open the 'Units' panel by clicking the corresponding name in the top panel or choosing the corresponding item in the main menu customizer.
Afterwards, choose a mode which allows you to work either with units or
groups of units. Note that unit creation is available in the 'Units'
mode only, while other options can be used in the 'Groups' mode as well.
