The logical organization of the Units form facilitates entering feature table information and makes it easy to drill down for more information. The "clone features" wizard makes the job of entering features for identical units trivial.
In the Corporate Edition and higher, the appearance changes to match the property type; the form shown is residential, and here is the commercial unit form.
From here you can easily drill down to tenant information, or a complete workorder history, or a complete expense history.
You can do free format input to keep information that is not otherwise provided for. And, as with the building form, you can link to and execute any information, data, or program you choose, without limit.
