Add the remarks section from ENR5.1 for restricted and danger areas to the What's Here section. 

We have considered this before but it would add a considerable burden to our data maintenance people, with little benefit as SkyDemon provides access to the ENR 5.1 documents anyway. We'd just be duplicating information.

I understand that it does not make sense to duplicate, but is there any chance to link the P,D,R area in What's here with the AIP ENR section ?
(such like open AIP ENR P,D,R descrption and search for the correct area ?) Have no clue if this is technically possible but would be great‌

I don't think it's technically feasible to open a PDF with a search active, and unfortunately there's little standardisation in ENR 5.1 documents as to how the area identifiers are formatted so it wouldn't work a lot of the time anyway. If it were doable, that's exactly the sort of thing we'd probably have done already, as it would help us with our data creation too.
