Congrats to Maxime Beguin on the success of Advanced Themer for Bricks. While it is not necessary to use any addons to make sites with Bricks, Advanced Themer hit a sweet spot in providing new features and tweaks inside the Bricks builder.
The plugin provides features such as the ability to create and manage CSS variables, a class importer, the ability to enable / disable options for clients, as well as shortcuts and additions to the Bricks editor. There are a number of utilities included, such as the ability to enable a light and dark theme for your site, a color palette generator, and the obligatory AI integration.
Advanced Themer launched in April and just reached version 1.1. While a lot of people have been using it on live sites, it is now officially out of beta.
