This repository is used as an online source of files for Aldaviva/VivaldiCustomLauncher to tweak the Vivaldi installation directory, which would otherwise be lost each time a Vivaldi update is installed. It allows me to publish changes to browser chrome resources, such as custom Javascript and Cascading Style Sheets, without forcing consumers to manually re-download VivaldiCustomLauncher each time.
These files go in Application\*\resources\vivaldi\ in the Vivaldi installation directory and are added to browser.html. You could do this manually, but I recommend using VivaldiCustomLauncher to get these changes applied any time you launch Vivaldi, even after an upgrade.
Make the browser's chrome appearance more minimal, enable maximum tab width, and fix one or two visual defects.
Add more keyboard shortcuts, and notify my password manager (using Aldaviva/WebAutoTypeVivaldiExtension) when the active window changes.
The Skinny theme is available on Vivaldi Community or in Skinny.zip.
