Provide more user defined string fields in the tag metadata. This will allow a text description to be entered for both the true and false case for a boolean tag, for example. Could also allow electrical drawing information for the IO point to be put into the database and displayed on the screen.

It's possible to add arbitrary metadata to tags in 8.0 via JSON editing.

Another use: Storing localized units (example... PLC is in meters, but display value on HMI needs to be in FEET. Both the conversion factor and the localized units can be saved. BETTER YET: create new permanent fields and automatically convert under the hood for localizing values.
Another use: Storing web links to help files for a tag

Furthermore, if description fields for the OFF / ON states of a boolean tag are added, there should also be a property for that tag that contains the current state description as a string.
Also, it would be nice to be able to do something similar for integer tags whose values represent a state (e.g. 0 - Stopped, 1 - Running, 2 - Faulted, etc.)
