Created attachment 154654 [details] Hide Column Dialog update Separator Line is one group and one group should be in one column at least if the space is available and as the dialog didn't increase in size, I suggest to make one column instead of 3 for Separator Line. Top: master Bottom: proposal
With larger controls as for gtk3 the dialog may grow in height. But I'm +1 anyway.
OK ..
Created attachment 154873 [details] Hide Column Dialog update 02 As Position is align to Height I added it there and now it's also one row smaller.
Looks good. Keep an eye on the vertical line of the labels, seems to be not pixel-perfect neither left-aligned. And last but not least the preview is quite small and lacks on a section title. OTOH, Width and Spacing below needs all the horizontal space.
Created attachment 154893 [details] Screenshot with the patch applied Comment on Gerrit: "Captions at Width and Spacing are right aligned. And it would be nice to start controls at the same distance, meaning all captions are in one box (one grid for all content). Style dropdown is a bit to small and the content is hard to read (screenshot at BZ)."
