Go-OO is a fork of OpenOffice that has quite a few impressive features which really ought to be in official OO, but for some reason or another aren´t, such as support for OpenXML, better Microsoft Binary support, Excel VBA macros, Visio diagrams and Word Perfect Graphics support. It also boasts significantly better start times -- at least on our poorly equipped test machine.

Better interoperability
Go-oo has built in OpenXML import filters and it will import your Microsoft Works files. Compared with up-stream OO.o, it has better Microsoft binary file support (with eg. fields support), and it will import WordPerfect graphics beautifully. If you are reliant on Excel VBA macros - then Go-oo offers the best macro fidelity too. If you expect your spreadsheets to calculate compatibly, or you get embedded Visio diagrams in your documents, you´ll want Go-oo.

Better functionality
Go-oo´s user interface is more familiar, with lots of small pieces of polish. We have built-in (working) multimedia integration on Linux, a beautiful solver component, and your Chinese should look sane. We also integrate with your system better by default: eg. enabling native file-selectors on Linux.

A Faster application
From first-time startup, where we sort I/O to reduce seek cost, to a highly optimised second start application and a systray quick-starter on Linux we are faster. We use less memory than up-stream, we link faster, use better system allocators, and don´t waste so much time & memory in the registry. Go-oo performance is hard to beat.

Faster code integration
Contributing code to go-oo is simple, and fast, following the traditional hackers´ process of peer code review: just mail patches to the mailing list, or when we get used to your code - commit your patch immediately to HEAD ooo-build: no CWS, no hours of tagging, paperwork, no specification, no hassle. Of course - if your patch sucks - expect to hear how it can be improved.
