I don't think any of the plugins come with instructions, and other than a few screenshots and brief description there is not a lot of information for these plugins.
The template system seems very confusing as there are core files as well as template files that need to be edited in order to make a change, there are lots of in-line styles used which makes editing harder.
Overall I am happy with the system, It will be interesting to see how this application develops and what will be included in core releases plugins wise, I don't mind paying $10 - $20 for a plugin it would be nice if there was a user guide to help along the way.
Another bit of feedback would it be possible to make the edit page a widget so it could be placed in the sidebar out of the way.
thanks
