Yes of course;
As a matter of fact I am digging around to gain as much information about using TBX as possible.
I think even before reading your reply, last night in bed I was reading up on my iPad mini and found the accompanying pdf of “Getting Started With TBX: Agents and Actions” referring to the accompanying TBX file.
What do I have in mind?
I work in home-building engineering and setup electrical and home automation circuitry. These installations need to be approved after a technical inspection by an accredited inspection company. To document the installation we use electrical diagrams but also need a kind of floor-plan illustrating how the the wiring is setup.
I am contemplating the use of the floor-plan / building layout as an adornment in TBX. Each TBX-note would represent a device of a specific type e.g. switch, luminary appliance or intelligent switch or whatever home automatin device or sensor.
What I would most certainly need is a way to export information, preferably to csv. (I know TBX does not do this directly)
E.g. some right-clicking would expose export / copy the pre-defined attributes to be pasted in a txt file and so on.
Notes would also contain documentation of the relevant devices. Not sure yet how: embedded in a note or linked to a note.
