Marquee promotional tile (1400x560) is included
Why it matters
The 1400x560 marquee tile is the banner Chrome Web Store uses when featuring an extension in editorial collections or category spotlights. Without it, your extension is ineligible for featured placement — one of the highest-traffic discoverability surfaces in the store. Extensions in featured sections see significantly higher install rates than those found only through search. While not a hard submission blocker, the chrome-cws-marquee-tile recommendation is followed by every extension that achieves meaningful organic growth through store discovery.
Severity rationale
Low because a missing marquee tile forfeits editorial featuring opportunities but does not block submission or break functionality.
Remediation
Create a 1400x560 pixel promotional banner highlighting your extension's primary value proposition. Save it to screenshots/marquee.png.

Design guidance: include the extension icon, name, and one-sentence benefit. Use a color scheme that matches your icon. Tools like Figma (free) have Chrome Web Store marquee templates. The image must be PNG or JPG; keep file size under 1MB. Upload in the store dashboard under Store Listing > Promotional Images.
