Colored numbers
On the ordered list block (ie. numbered), you can now apply colored circles to the numbers to improve readability:

See the quick intro video:
A few notes:
- you must select the numbered / ordered list, not unordered list
- this appears in the style tab of the block, which is the half-white-half-black circle
- this does not work with reversed numbers
- list start numbers up to 20 are supported
- you must select the list block, not the individual list item
