Well it seems that nobody with good coder skills is not interested to port netsurf, wich is MUCH easier task than make Amay work with AOS or make Aweb support CSS.
it is easier add CCS and good JAVASCRIPT to ibrowse or Aweb
even there is the full aweb source code
I'm sure anyone with good skills can do it and make them run on a standart A1200 /020 +8mb ram/AGA only
the problem is the hard work..nobody will make it for free
