Created attachment 203247 [details] Screenshot Large icons in stacked variant of the VT are drawn on top without any margin. It should be centered horizontally and vertically. The tab width does not adjust for long text, here the example is "Slant and Corner Radius" for the Position & Size dialog on objects.
Expand vertical tabs for long text. You mean dynamically? So width can vary between dialogs? I have a hard time envisioning what will change and the impact would be I do like UI consistency/ stability. I find it rather distracting if the vertical tab bar width being calculated on content and having a different width for each dialog individually. I personally would even consider dropping the labels and instead showing a mouse over tooltip for the label (so icon based system, like the main toolbar). But well that requires 'expressive' icons, but the most meeting that requirement, I think

1. I would consider using shorter labels, and compensating with tab section titles as necessary. In the screenshot, it could be: Size & Position Rotation Slant & Corners 2. As a fallback, though - don't expand the tab nav-pane horizontally to fit the text! :-( Instead, I suggest you arrange for the text wrap onto a second line.
The tab size adjusts in case of small icons but does not for large. I adjusted the summary.
Expanding the tab looks okay for English but might become an issue when localized text is even longer. The alternative to wrap text into a second line requires the RenderContext for a precise TextRect() calculation in SvxIconChoiceCtrl_Impl::CalcBoundingHeight(). And since we have an equidistant grid behind the items it looks a bit awkward anyway.

Abandoning the patch https://gerrit.libreoffice.org/c/core/+/192170 which tries to solve the issue by resizing the item.
