Hi everyone,

This is Vithya from Perth, Western Australia. My apology as I have been more of a silent follower the group, and haven't gotten involved much due to my current workload.

Congratulations on developing Ace! I have been producing Accessible ePub3 Publications for my organisation and been following this space for quite some time.

I would also like to provide my feedback about Ace :)

Kind Regards,
Vithya Vijayakumare | VisAbility

Great, very much looking forward to your feedback!

Now, Ace reports an error when accessMode,
accessModeSufficient, or accessibilityFeature is
absent.  We are wondering if Ace will suggest
particular values of these metadata. Is such
an extension already planned?

Yes, this is definitely on our radar, but we're not yet sure we can make it in v1.0.0.
This is tracked as issue #35:

We are also wondering if the use of Javascript might
cause performance problems if Ace starts to examine
all characters (e.g., whether every CJK character is
in JIS X 0213) for example.

I'd be happy to learn more about any performance issue that you may encounter. Feel free to report issues directly to our tracker:
