What to put on a default Amiga OS install

[amyren]

It's only for WinUAE I don't have an Amiga anymore, until I get an FPGA arcade. I'm looking for some hot picks.

If its for WinUAE, why dont you just get the latest AmiKit version, and many of the most common tools and programs will be included on the basic install. And then you will be sure that all the needed libs and datatypes etc are the latest stable version, because all the included programs and system tools are tested to work together.
Look at http://amikit.amiga.sk

There are other packages as well, as AmiSYS that could be worth checking out.
