Short list:
- Positioning widget
Now one can position objects with either address,map or coordinates through simple interface.
More about this can be read on Henri's blog. - A multipurpose Chooser widget
With easy configurations you can use this widget to search for all kinds of DBA objects inside your site.
It's packed with configuration options but one can also be lazy and let the widget decide what fields to be shown
from selected type and how. - Added creation support for the Chooser widget
Now one can even create new objects through the widget if the results don't satisfy.
More about this can be read from Henri's blog. - Tag selection widget
This is a visual way of handling tags on objects. (I must post some screenshots about this...) - FCKeditor widget
I started adding other WYSIWYG editor to midcom. Currently midcom uses TinyMCE
