Misc PhAb questions

Hello,
A few quick ones:

In PhAb, how can I add Include paths in the same way I can add link lines in Project->Properties…? I have my own header files and need to add them to the include paths via a -I flag (that’s an upper case ‘i’ not lower case ‘L’).

Again in PhAb, which is best file to define my own structures? I put them into my main functions file (main.c), but it seems the proto.h file cannot see them there, so functions in proto.h which refer to my structures cause compile errors.

Are there any good examples of using PtRawList? I’ve seen the docs, but I don’t really have a scooby about this widget, so they don’t make much sense to me.
