SCID might annihilate chessbase from the market, once
it has got expanded commenting features ;-)
Like in chessbase one can mark ranks in different
colours thus visually highlighting some comment e.g.
"after the bishop move white controls both long
diagonales" while on the board these are coloured
yellow for quicker realisation.
or : white threatens 4 pieces, while black threatens
only two pieces, while the threatened pieces are
coloured red, so you can see them immediately.
during animation replay this should be visible. SCID is
then also improved for training work. I think one can
work quicker and more efficiently with annotated games
with arrows and visual information like that.
maybe there are PGN tokens for this already ?
