I know that Alex has said that fixing the replays is on his list of things to fix and that's cool.  It'll be nice to have reliable replays once again.

I would like to be able to review just the last 5 or 10 moves.  On a longer game (50-60 turns) the entire game replay can take a really long time.

A pause function would also be nice. I like pistos' version of game replays.

Features akin to this will be in the script pluto and I are currently working on:

yep... a replay pause functionality has been written, just not implemented in the script yet...

more to come..
