This is a request to allow customisable tool icons. Currently, every tool of the same type gets the same icon. For example, if you have a number of web content tools, they all have the same icon. See screenshot.
I propose that when rendering the tool list, the portal checks for a tool property (tool-class). The value of this is then output into the markup for the tool, e.g.:
<span class="toolMenuIcon icon-sakai-iframe TOOL-CLASS-HERE">Web Content</span>
Corresponding CSS would need to be added to portal.css for the actual styling to occur.
This is the approach taken in uPortal.
