Created attachment 198874 [details] Screenshot of the current items in the toolbars When in "Tabbed" notebookbar or "Groupedbar Compact" UI toolbars layout mode, when you have a shape (or an image) selected in Writer / Draw / Impress, as you can see in the attached screenshot, you have this huge amount of horizontal space consumed by the fact that the area's fill mode (solid vs gradient etc.) is a separate combobox widget from the actual value of that fill (the color or the exact gradient). A lot of precious horizontal space could be saved by combining these two into the same popover-style dropdown widget than the one that shows up when you click the fill color (i.e. the one with the colors palette, like in my screenshot). This would allow users to see more of the rest of the toolbar, especially on lower resolutions screens (like my laptop or my 1600x900 monitor). The unified widget's clickable item on the toolbar could use the appearance of the current 2nd fill color/gradient preview menubutton widget; it's fairly obvious that it is a "color" or "gradient" thanks to the visual preview. Basically, the idea is to merge the mode combobox into the value combobox. ---- Arguably, the same kind of combination could probably be done for the "Line" settings too. By making these changes together, you could easily halve the horizontal width required for this section of the toolbar.
Another situation where this would be tremendously helpful (beyond sub-HD screen resolutions) is when the app is not maximized, or half-tiled on the screen.
