Known Issues

• Labelling standalone whitespaces will not work.
• Trailing and leading whitespace will be included in selection but not rendered.
• Label colors are generated from the first 6 characters of its own MD5 hash, which may clash and have low contrast (native HSL doesn't work fully with LS).
• Each selection renders best with 1 label only. If you need multiple labels, create multiple selections.
