Hi Chewie... haven't actually tried a timed blind scan with yesterdays build, but yes it does seem faster and list more transponders.
The sat finder seems to react more quickly to a signal too.
If I see an upgrade #20+git+649 etc. for the blind scan module, I can tell it changed from the prior build and that the coders tweaked it.
In regards to the earlier post for TSPanel, some others are also having problems once loaded. One op claims that loading 7.2. first and upgrading to 7.3 cured his crash problems. I still haven't tried doing this. But now that you can edit the sat.xml file with DreamBoxEdit, it seems a moot point.
