So far, so good. Although I must say I haven't tried anything too fancy yet.
I did find a bug in ea7 with syntactic predicates, but it seems to have been
fixed in the current repository version.

One thing I would like to see is better messages from the tool in the case
of ambiguities. The "Decision can match input such as ... using multiple
alternatives: 1, 2" are not too helpful when dealing with complex rules.

Not really, simply because I haven't had a chance to check it out. I'll give
it a try.
