Hi Tomáš,

first, thank you for the answer.

So this sentence of the wiki [1] is wrong (documentation of the command argument)?:
> Command to use for typesetting the title; overrules all other styling. First argument is the number, second the title text.

If I see it right, `style=` only affects the typesetting of `#1` and `#2`, so I need setupbodyfont _and_ switchtobodyfont, didn't I?
Also, when I want #1 and #2 to be in different sizes, I choose the "base" size with style=\setupbodyfont and adjust it further with switchtobodyfont just for one the the argument?

All in all, the correct documentation would be:
> Command to use for typesetting the title. First argument is the number, second the title text. Styling of these parameters can be achieved only by specifying style=.

This produces an extra line break between '#2' and ':', I don't get why. Otherwise, it looks quite nice.

That works, thank you!
