Small user script: Visual identity for multi-instance Trilium setups (browser tab prefix, border, favicon)

[Br0kenSilos]

Hi everyone,

I run several Trilium server instances (Work, Personal, Business, Legacy, etc.) and often keep them open in multiple browser tabs. I was finding it difficult to quickly tell which instance was which, so I built a small frontend script that adds visual identity per instance:

• adds a bold prefix to the browser tab title
• optionally draws a colored border around the main UI
• optionally creates a custom favicon (solid color + letter)

Repo: https://github.com/Br0kenSilos/trilium-instance-name-on-browser-tab

If this is helpful to anyone else running multiple server instances, feel free to use or adapt it as you see fit. Keep in mind I am not a developer by any means and had a lot of AI help on this one. But so far it has worked pretty well for me and I figured, perhaps someone else will find it useful.

And a very special thanks to @zadam for creating Trilium, and to @eliandoran and the Trilium Next team for keeping the project alive and moving forward. I cannot tell you how much Trilium has helped me get organized.

This script is an unofficial customization and not associated with the project — just something I made because Trilium is, well, very awesome and cool!

Thanks, and hope this helps someone.
