Step 1: Download the Liquid Glass theme
Decompress this zip file, and put the 2026 folder into the Themes folder as shown. All retroStrip themes reside in your Documents directory.
Step 2: Update the settings file
Open the retroStrip-settings.json file in a text editor. Look for the "available themes" and carefully add 2026 as shown. Be mindful of commas, and don’t add extra spaces. Save and relaunch retroStrip, and the theme should be available. That's it!
Theme notes
You can use the 2026 theme as a template for your own themes. Make sure your theme has equivalents of all the images in the Chrome folder - maintain the file names and dimensions.
For icons, your theme should have equivalents of the icons provided, but you can add as many additional icons as you like.
Themes can have any name you like - just make sure the name of the folder matches the text you add to the settings file.
