Convenience: "We noticed you have the word 'attachment' in your email body, but no attached files". It's nice to have, but not something I couldn't live without

Convenience: "We noticed you have the word 'attachment' in your email body, but no attached files". It's nice to have, but not something I couldn't live without, either. Example: This exact feature in Gmail. Expanded capabilities: A vector editing program that exports to SVG. I couldn't realistically complete the task of creating complex vector images by writing raw SVG. Example: Sketch, Adobe Illustrator. The marketing catch: Convincing people that #1 is exactly as valuable as #2.
