my suggestion, drum roll please, a personal notepad for game notes.
Okay- maybe I'm just a hack, but sometimes i see a board i haven't played in a while, and i kinda wonder "what was my contingency plan again?" Or, "where was i going with this?" after my opponent manages to foil the umpteen conditionals i spent half the night entering...
I would think it was just the aforementioned hackery .... but the SchemingMind.com site has one and c'mon... RedHot is a way way cooler site. Way.
Its seems like a pretty easy thing to add, so I'm left to figure its been probably been suggested like, a bizillion years ago, but either way- me & my lil ol' brain think it'd be kinda nifty.
