Describe your change:

• Add an algorithm?
• Fix a bug or typo in an existing algorithm?
• Documentation change?
  • It is good to have a field for extra/additional information if the user wants to specify or tell something else that doesn't fit any of the provided fields in the issue form.
  • Blank issues were disabled in favor of the miscellaneous/another template, which asks the user for at least a bit of information, rather than letting the user create a blank issue. This can be better for the maintainers when checking out the issues, IMO.
