I'm afraid you totally misunderstood the workings of Elastic Tabstops. All you need to implement ET is a text control that allows setting tab widths in pixels
Ahh .. I see.
You mean postscript.
Sadly the world has been crippled with microsoft rubbish for 30 years making a decent interface
almost impossible.
Perhaps super sized kerning on variable width fonts...
Hmm... how about a font with multiple pixel widths for whitespace characters and everything else
the same... again it would need work but maybe it could come close and wouldn't need to have
compatibility issues. Different blocks of text could use different combinations of character widths.
I'm still unclear why limited pixel spacing in a microsoft world is needed though but I guess
others have seen the benefit.
