First post on this site. I think Hubski Enhancement Suite needs to exist.
To add to Kafke, there isn't much of a need for a Hubski Enhancement Suite yet due to the fact that the wonderful mk implements features about as fast as we can throw them at him. You can add suggestions using the #suggestions tag. I recommend you read through the old suggestions and features (see: #hubskiblog) and read those discussions to see how things happen and get insight on what features exist and why. It's really interesting. The server is in lockdown mode so give it some time until we're back up and running to see the full history of tags and posts. We really took a beating tonight.
Hubski Enhancement Suite as well as other Hubski tools can be found on the tools page. There's a link down at the bottom of the page as well. It seems Hubski Enhancement Suite is a javascript for use with greasemonkey and the like, while the other tools are chrome extensions.
Unfortunately HES development has fallen to the wayside - as I have since joined the hubski team - but if anyone wants to pick it up they're welcome to.
