I would love to see some speed improvements to Synchronize It.
Some ideas I had were:
1) MultiThreaded directory crawler - Would check directories with a pool of threads.
2) Implementation of rdiff algorithm to support differential file comparison and the moving of file deltas instead of entire files (http://en.wikipedia.org/wiki/Rsync).
3) Tree view of directory changes or some sort of rollup when directories are on one side and not the other.
Keep up the great work!
