My killer shape-related feature request would be for wmf/emf import to pdfs to remain vectors. I use the Microsoft Charting controls to place graphs in PDFs. The charts can be exported to vector format wmf, but loading into GemBox causes it to be rasterized. I increase the resolution and scale the picture, but printing is still pixelated, especially axis labels.

In our company, we have some instructions, and many various manuals in docx where people could add different kind of shapes from Word...
We require all shapes (not only basic) in the future release.

Please add the arrow shapes (horizontal, vertical and rotated arrows).
