Yeah....I did play with that, and it was okay. I think Im just too set in my ways with editors to be honest. I "do" like ones that include debuggers etc. and if there was some sort of "link" to YAPE or Minus4, so you could single step through your source while it stepped the code, that WOULD be cool....
SNasm is freeware too BTW. It also has a couple of new options to make C64 and Plus4 basic run commands for you.
opt prg ; save 2 byte PRG header
opt plus4 = MainStart ; save BASIC command to RUN program
org $1010 ; "normal" start-up ORG
MainStart:
sei
and so on. The "opt" plus4 takes the address you specify and makes a basic line pointing to it, and the "opt" prg makes it a .PRG file for you
I got fed up making basic lines by hand 
It also has shorthand for &255 and >>8 stuff like this...
lda # sta $fffe
lda #>IRQ_Handler
sta $ffff
and lastly something I pinched from the old PDS code.. a HEX command...
HEX 0f071205200d0f0e09140f1200
Which allows Hex arrays to be entered and displayed a bit easier
I'll update it and put it up on the web site in a bit if anyone wants to play with it. The whole games built with it so it should be fairly stable.
Also does "pretend" ORG's.
org $600
Blah...
pcorg $600
Code to copy.
This lets you build code that will be moved to the correct location later, which is dead handy for things like the uploader which runs at a lower address, but build in a single block.
