- Databases fully compatible with mainline Scid and extensively tested
- Play chess on the internet or against the computer
- Computer Tournament feature
- Interface overhauled and debugged, including -
- Rewritten Gamelist, Ratings Graph, Analysis Engines and main window
- Drag+Drop support for Windows, Linux and other Xorg systems
- Tree window has embedded win/lose bar-graphs
- Book window allows for two books, and tuning has delete book move
- Clickable variation arrows
The 'rewritten' gamelist has no filtering like Scid has. Thats not useful. Also Scid, like Chessbase has a click-target-square move enter feature and Scid vs PC has not. Misses a few other features Scid has. Therefore it has fixed the nasty bugs known from Scid on Windows. But without the above two features i can develop no real workflow with it.
