This seems very similar to True Knowledge, which has been in Beta for ages, and not as other people suggest, Google

One tracker that hasn't been mentioned that I'm enjoying using is Roundup. It's written in Python, uses the TAL template language, and is really easy to customise if the base install doesn't suit your needs. I really recommend that you check it out.

The biggest problem I find with OO.o is the unpolished and sometimes downright stupid UI design decisions. For an example try this:

• Open a new document (e.g. presentation)
• Create a new shape (e.g. rectangle)
• Try and make it a non standard colour (e.g. Slashdot green)

You can't easily. To do this you have to right click on the object, select styles and formatting and go to the Colours tab, where you encounter the most unintuitive UI for adding colours to the internal palette. There's not even the Saturation/Hue picker for new users. Just RGB values. Frankly: absolutely appauling. And don't even bother transferring the document to another machine and trying to modify the colour, it will drive you insane. I appreciate all the effort that's gone into it, but there are places where it is a battle to get it to do what you want. And that isn't productive or fun.
