The plans for widgets have changed somewhat. Instead of 4 or so
variants, there will instead be one unified widget that chooses
different layouts depending on its size. The first one added is the
full widget, which shows more controls as long as theres enough
space.
Improve the black theme selection color by merging it with the dark
theme selection coler. This makes the selection color both more
noticable and reduces the style complexity that came from having to
manage two different selection colors.
