According to Engadget, iOS 26.1, iPadOS 26.1, and macOS 26.1 were all released today with significant Liquid Glass customization features that allow users to apply a frostier, more opaque appearance to the interface. The new tinting option for notifications and tab bars can be found in the Display & Brightness settings under the Liquid Glass section, joining existing customization options that range from fully transparent to high-contrast modes. The update also brings back the Slide Over feature for iPad users, which has been reimagined to allow window pinning, hiding, and resizing capabilities for better multitasking control. Engadget notes that the Liquid Glass aesthetic has been divisive since its announcement, with their own team split on the design philosophy. This latest update represents Apple’s continued expansion of visual customization tools.

The Accessibility-First Design Revolution
What Apple is demonstrating with these incremental Liquid Glass customization options is a fundamental shift in how major tech companies approach interface design. The traditional one-size-fits-all aesthetic is being systematically dismantled in favor of what I call “accessibility-first design” – where features originally developed for users with specific needs become mainstream customization tools. This isn’t just about adding a frost effect; it’s about acknowledging that visual preferences vary dramatically across user demographics. The growing emphasis on accessibility features across the industry suggests we’re entering an era where personalization isn’t just about wallpapers and widgets, but about core interface rendering itself.
iPad’s Productivity Identity Crisis
The return of Slide Over reveals Apple’s ongoing struggle to define the iPad’s productivity identity. This feature’s journey – from introduction to removal to reimagined return – demonstrates how Apple is grappling with tablet workflow expectations. The current implementation, allowing windows to be pinned and hidden, suggests Apple is finally acknowledging that tablet users want desktop-like control without desktop complexity. This represents a maturation of Apple’s tablet philosophy, moving beyond the simplistic “iPad can replace your computer” messaging to a more nuanced understanding of hybrid workflow needs. The ability to resize and aspect ratio these windows indicates Apple is taking productivity customization more seriously than ever before.
The Coming Wave of UI Personalization
Looking 12-24 months ahead, these Liquid Glass customization options are just the beginning of a much larger trend toward deeply personalized interfaces. We’re likely to see Apple and competitors introduce AI-driven interface adaptation that learns from user behavior and environmental conditions. Imagine interfaces that automatically adjust opacity based on ambient light, or color schemes that shift throughout the day to reduce eye strain. The human interface guidelines that have governed consistent design for decades will need to evolve to accommodate this new era of fluid, adaptive interfaces. The challenge will be maintaining brand identity while offering unprecedented visual flexibility.
Developer Ecosystem Implications
For developers, this move toward system-level UI customization creates both opportunities and challenges. Apps will need to be designed with variable transparency and contrast in mind, testing across multiple Liquid Glass settings to ensure readability and aesthetic coherence. The iOS developer ecosystem will need to adapt to these new variables, potentially requiring more sophisticated design systems that can gracefully handle user-controlled interface modifications. This could lead to a new category of design tools specifically for testing across customizable system interfaces, creating opportunities for specialized development platforms and testing services.
