There's a new version of MySpeed which now includes a download manager for SCDB.info. You need a paid account with SCDB to be able to use this.
I also improved the import screen layout a bit.
The previous release broke importing of CSV files, so I've fixed that.
What I'm going to do next is redesign the import screen a bit. Now that importing is much faster there's no need to run it in the background. I'll change it to be like the download screen with a progress bar and status message at the bottom of the screen.
