Hi Jomshaper
The “ARTICLES” component only allows the inclusion of Joomla and K2 articles, which causes some design flaws and means you have to spend time trying to resolve this issue. My suggestion is to also enable SPPB to do the same as with Joomla and K2, since it is possible to create a category and link it. I don't think it would be that complicated for good developers to implement this functionality.
I hope you will consider my proposal within a reasonable time frame.
Regards
