When a tool has gajillion features, the tool-bar/ribbon will end up seeming arbitrary anyhow. Categorization on a larger scale is simply a hard problem, partly because categories will start to overlap. I'd rather both orgs stop shuffling it around because one ends up using positional memory anyhow: keep the devil one knows.
Perhaps its better to leave most features in the top drop-down menu and let the user customize the tool bar (but still have a default set). The top drop-down menu could have a button on the right side that allows one to "pin" that feature to the tool-bar. People tend to use a limited set of features based on their shop preferences or domain. They can pin their favorites. If pin choices don't fit on one tool bar, have an option to either show multiple bars, an as-needed pop-down second+ bar, or left/right scroll-arrows. Assigning one's preferred keyboard shortcuts would also be nice.
That being said, L.O. Base sucks rotting eggs. MS-Access is far superior.
