Textualize/textual v0.43.0

The Nothing to See Here Release

on GitHub

The highlight of this release, is the new keyline rule which draws lines around widgets in the margins.

This is similar to border, but keyline can overlap with neighbouring widgets. Here's a screenshot. Note how the green borders around the widgets intersect with each other.

See below for the full changelog.
