Downloaded and tried it. Didn't appear to find my favorites, I had to add them "new."
Added about 6, requested update, got the download but there was an error on each one trying to do the update. Restarted and got the same error.
Developer hasn't posted in the support thread since 6/6 (although as an S-Mod last on was last night) with 4+ postings since his last post have gone unanswered.
The 6/6 post said he was working on a re-write so it's possible what's online now will be superseded. Last update was 2/08 so the current version seems feature frozen.
Summary: looks like a nice attempt, but (for me) doesn't work and what is online now isn't being actively supported. Hopefully the rewrite will have some Good Stuff in it.
