So far, I have full baseline feature support for everything back to Mosaic, including Lynx, IE3, Netscape3, Opera3, and many others.
At the same time, still including advanced features like client-side PGP for browsers which will support it.
Every browser presents its own challenges, and it is not always the oldest ones which have the dumbest behaviors.
My intent is to promote interoperability and offer something as an alternative to today's near-monoculture.
