As long as we're making a wishlist...I think the most crucial
thing might be some way to see a scan line as it's being drawn.
As you step through the instructions inside a kernal, maybe
there could be some kind of visual indication on the screen as it's
being drawn indicating "electron beam is here now"...I don't know
how hard that would be to intigrate with how stella's doing all
of its difficult work...

At this point beggars can't be choosers and anything with breakpoints and single-steps would be a huge windfall for the more novice programmers here on Stellalist.

That being said. I'd like to see cycle counters linked to addresses. If you could initialize a cycle counter when the code hits one or more addresses you could measure exactly how long your VBLANK is taking (which typically varies from frame to frame depending on game state) or you can set it up in your kernel to find scanlines going over the limit, etc... Then you'll never have to spend long figuring out why the screen glitches.

I'd also like to see some way to customize the debugger so you can, for instance, display hex or decimal. I still think primarily in decimal.
