I have no connection or affiliation with this product, but I enjoy a good ASCII/Unicode chart in code—a picture is worth a 1k words—and I've been leaning on https://monodraw.helftone.com/ lately for my text drawing needs.
I remember ASCII and ANSI art editors that were meant to be used with mouse ever since the DOS times (often distributed through and for BBS) in the late 80s/early 90s.
That's an awesome product but being Mac only is a no go for me. Electron / Web app is such a common product model, no idea why they didn't embrace that.
Are there serious interactive image editors that don't require a mouse? For symmetry's sake.
