It would be very convenient if projects could use some kind of relative path scheme for their files.
One benefit would be that a project could easily be reconfigured if it were necessary to relocate the files.
It would be even better, though a lot more work, if #include path processing could support the same scheme.
Together, these would also allow an entire project to be wrapped up in a zip or similar archive. The ability to create such from within 010 Editor would be especially nice.
