Brian Lambert is about as skilled a UI programmer as you are likely to meet. He was one of the early developers at Onfolio, a startup and product that Microsoft acquired and out of whose ashes Writer arose. IIRC Brian was long gone by the time we started working on Writer, but plenty of his code ended up shipping in it.
I imagine there must have been scores of more colorful comments by Brian and others that got scrubbed before the open source release.
Secretly one of the better authoring tools out there, but handicapped by an association with "Windows Live" (worst brand ever) and by an overly Windows-centric architecture. This tool should be rebuilt not under .NET (even with MONO) but under something like Electron, for the 3 major desktops, keeping the same clean round-trip HTML/Preview we loved in the old, and adding Markdown support.
