Hi,
Although we've been working on these 2 big issues, but there is not much in the progress, to be honest. Both issues are related heavily on JavaScript. We had a draft solution for cloning wysiwyg, but WP changes its code and it doesn't work anymore. We're working on using pure JavaScript to work with TinyMCE instead of using WP's code.
Regarding the group issue, we have a fix for Javascript to make nested group works. This will be finished soon.
Our plan in near future is:
- Finishing the development version on Github to release 3.8 version. It's a major change in the plugin core.
- Then work on wysiwyg issue
- Then group issue (probably in parallel if it isn't related to changes in 3.8 version).
We're trying our best. Please be patient.
