Re: Using proportional fonts in Gnus

[Richard Stallman]

    For instance a "super tab" text property saying "align to colum N (or
    leave M units of whitespace if already there)"; maybe some degree of
    indirection would be useful so one need not rewrite the buffer text to
    change N dynamically.

There could be a kind of alignment property which says "align the same
as position P, plus OFFSET."  (P would be a marker.)  Once we have the
long-requested functions to compute columns in pixels, this would be
easy to implement.
