Ah yes, text editors, archivers... forgot about those! Some of the ones cfrom my list are pretty useless now of course other than for nostalgic reasons, like the BBS and terminal software. However, I was thinking of starting the old BBS up on the net for fun.
Those are all good software on a amigaos 3.0/3.1 setup, however some of them have been replaced by other/better software and some of them are not needed with for example amigaos 3.9 (you could use amidock to launch programs for example). And if you're using amigaos 4.0 or 4.1 even more of those software are replaced with better options.
Regarding a startmenu amistart is a good option.
