Drawings are nice, but PLEASE add the ability to embed hyperlinks within the graphics.  It would be wonderful to link from either text or shapes within the drawing tool to other web content. And if these drawings with hyperlinks can then be inserted into Google Sites pages, you will have solved one of the biggest limitations that Google Sites has, which is the ability to include interactive graphics and visually appealing pages.  With the integration of Google Drawings and hyperlinks within drawings, the site development tools will become much more powerful.

Thanks for continuing to improve Google apps!
