I'd like to start a discussion about our default palettes. Since Jon implemented the feature years back, I've done many casual surveys of which palettes designers are using and which ones designers want. My suggestion is that we sanitize our current collection of palettes to make inkscape easier for common tasks as well as remove the bloat.
I would only change one thing. Change the default color palette such that it does not require a scroll bar.
If this is difficult to do because you do not known the users window width than create another option next to Size, Width and Wrap which is called Fit. The Fit option will always fit the width of the palette to the width of the window (Maybe it wraps if the size of a color cell drops below some minimum.)
