I would like some free text fields for devices, for different purposes, such as:
Alternative names/Purpose/Description (for when users tend refer to the device based on what it is used for)
Location (because while tagging is good for grouping devices, it is less ideal for specifics)
Special considerations/Things to note (things to keep in mind should the device need to be replaced, repeating issues, etc)
When and from where the device has been purchased
Planned date/year of replacement
