How do I add Polarr to the Photography section of the Ubuntu App Store?

Polarr is a photography application and should be discoverable under the Graphics and Photography categories of the Ubuntu Software Store. I can find Polarr in Ubuntu Software by directly searching for “polarr”, but Polarr does not show up under the Photography category. I’ve looked through the Snapcraft dashboard ( for an option to select categories, but I did not see one.

I use electron-builder and have set the category to “Photography” in my package.json file:

  "build": {
    "appId": "co.polarr.photoeditor",
    "linux": {
      "icon": "icon",
      "synopsis": "Powerful and easy-to-use photo editor.",
      "description": "Used by the world's most professional portrait and landscape photographers, Polarr offers advanced auto-enhance tools and sophisticated filters to edit every detail of your photo.",
      "category": "Photography",
      "target": [
    "appImage": {},
    "snap": {
      "confinement": "strict",
      "summary": "Powerful and easy-to-use photo editor.",
      "grade": "stable",
      "stagePackages": [
      "plugs": [

Categories in the Ubuntu 16.04 Software Store are completely broken and I’ve filed a separate bug report for that:

This is what I see in the Ubuntu 17.10 Software Store’s Photography category (missing Polarr):
