1.) IncludeFile and XIncludeFile should always be relative to the File's Path, they are called from, not from the main compiler-File.
Example showing the problem:
IncludeFile "var.pb" ;How should var.pb know, where it comes from?
A possibility to nest IncludePath would be nice too, perhaps using EndIncludePath to finish this (PB-steady syntax)
DoubleClicking on Test.pb gets me to the file (it's opened in the ide)
DoubleClicking on Frame1/Inc.pb doesn't do so, since it's in a subfolder defined by IncludePath. Shouldn't be such a big problem to get this working, should it?
