Hi again
Generally I want to invest my time into something that is future proof. So it will need to work in CS CC. ID 10 and onwards.
Let's just stick to my fist idea for a moment. For the moment I imagine my project to be a floating pallet. And ideally that pallet interacts with the open document. That is what I meant with interacting with the live InDesign.
I also understand that the paragraph style pallet access a lot of "messy" information. To look at formatting of the font in kind and size with a "few" variables could be presented in a spread sheet when looking at many para styles at the same time. However to look at the GREP code of many para styles at the same time might need a different approach.
Anyway my point would be to call up n styles at the same time and edit the GREP code side by side.
If every open style has an "Save" or "Update" button and I would be able to see the effects on the ID file without closing the palette that would be close to what I want to achieve. I am very aware that I am dreaming very much beyond my abilities here. -)
I sense this need to work very close to the core of InDesign.
So all this makes me think I will be best off to do this in C++.
