### Description There are many advantages to web app manifest - theme colours, install-to-homescreen, and more. ### Proposal I propose that GitLab be delivered with a `manifest.json` linked from the index. This manifest should provide a theme colour and a background colour (suggestion: #fc6d26 for theme and #292961 for background). Background colour could potentially be configured per user. ```json { "name": "GitLab.com", "short_name": "GitLab", "start_url": ".", "display": "standalone", "background_color": "#292961", "theme_color": "#fc6d26" "description": "The best darn git host on the intertubes.", "icons": [{ "src": "https://assets.gitlab-static.net/assets/favicon-075eba76312e8421991a0c1f89a89ee81678bcde72319dd3e8047e2a47cd3a42.ico", "sizes": "48x48", "type": "image/png" }] } ``` This is a small, easy change which could provide tremendous utility for users, and is open to progressive enhancement in the future. ### Links / references https://developer.mozilla.org/en-US/docs/Web/Manifest
