Here is another one I found. I wonder if it should count under this though:
#441183|Dakarete ageru!|7,111
A significant number of kanji have their readings specified, and it is definetely helpful for reading, but a lot of the (mostly simple) ones have their readings dropped.
Another thing this volume does is using both the reading and the kanji to communicate a mix of both - For example 表情 (ひょうじょう) is annotated as かお which makes sense but only if you know both of those words I suppose
