Darktable pretty messed up ux thanks to mismanagement, lack of direction and hobby programmers that often leave the project. (there is even someone trying to fix it with a fork https://https://ansel.photos/).
I applaud both Darktable's and Ansel's efforts, but they both have a looooong way to go with their UI. Spacing, contrast, fonts, it looks like they never received contributions from people with design skills. Blender looks way more polished in comparison.
