I've been meaning to make comics for a very long time, and somehow it took a HyperCard game jam to actually publish a thing that resembles a comic. HyperCard as an art program is really quite nice for these storyboard-esque scenes - just rough enough that it feels 'okay' to create artwork that isn't precisely polished.
However, the programming aspect of HyperCard was painful enough that I'm not sure I'd want to revisit that bit. Maybe one of these days I'll end up making my own HyperCard-esque paint program...
