One little request: The built in AC3/DTS file source filter tries to handle E-AC3 but fails. It would be great if that could be fixed. I can see 2 possible fixes:
(1) Just tell the filter to not handle E-AC3. Or:
(2) Add E-AC3 support to the filter.
FWIW, orbitlee has made a mod which enables E-AC3 support. Here's the download with source code:

He didn't get AC3/DTS to work properly after the mod, though, so he disabled AC3/DTS in his modded filter now.
