Visual cues for your split-screen tabs
What you get
Clear workspace grouping, zero confusion
Clean color cues that help you navigate multi-tab split layouts at a glance, without altering your page content.
Spot grouped tabs instantly
A slim, vibrant accent bar links tabs in the same split-screen tile, so you never have to guess which tabs are paired.
Colors that stay readable
Evaluates your active theme background and automatically skips low-contrast colors, keeping indicator bars crisp in both light and dark modes.
Hover to reveal links
Hovering over any tiled tab brightens the accent bars across its entire group, making paired tabs obvious before you click.
Focused active view
The active tab shines at full brightness while background tiled tabs are gently dimmed, keeping your attention where you are working.
Adapts to your layout
Full support whether your tab strip is at the top, bottom, or running vertically along the left or right edge.

The story
Why I built vivaldi-tile-viz
The problem
You tile two tabs to compare docs side by side, switch to another tab, and come back. In a busy tab bar, there is no visual cue showing which tabs were tiled together. Finding paired tabs means clicking through them one by one.
What I built
Standard browser extensions cannot access Vivaldi's tiling state, so I built a native UI mod. It links paired tabs with theme-aware accent colors and real-time hover cues—running completely locally with zero network calls.
What you get
Every split-screen tile is instantly recognizable in your tab bar. Paired tabs share a clear accent bar that stays readable across every theme and tab strip position.
