Is there some language / toolkit that you would
prefer for debugger GUI (over Python / Gtk)?
I'm not fixated on debugger GUI being part of
the Hatari Python GUI...
I don't have strong preference.
Personally I would be most pleased at anything that is cross-platform,
easily shippable for a release, and has a good response time. I end up
using both Linux (at home) and Windows (at work) when I'm coding, and I
much prefer Hatari to Steem even on Windows (I trust the code more :). I
also collaborate with several people who use Macs.
From experience it can get really painful if single-stepping and refresh is
too slow, but that not be down to the GUI platform. So I'll test with
python and GTK and see how well it fits.
