Editable browser tab title for distinguishing multiple open PAN-GO tabs

[tmushayahama]

Summary

Allow users to distinguish between multiple open PAN-GO tabs by dynamically setting — and optionally editing — the browser tab title. Currently all tabs display the same static title ("PAN-GO - Human Functionome") regardless of the page or gene being viewed.

This is especially important on the Search Results page where users frequently run multiple searches in separate tabs.

Current Behavior

• All browser tabs display the same static title: "PAN-GO - Human Functionome"
• No way to tell which search or page is open without switching to each tab
• Users comparing multiple gene searches must click through tabs to find the one they want

Proposed Solution

Phase 1 — Automatic Dynamic Titles (low effort, high value)

Set the browser tab title automatically based on the current page:

Page	Tab Title
Home	PAN-GO - Human Functionome
Gene detail page	BRCA1 - PAN-GO (shows gene symbol)
About	About - PAN-GO
Help	Help - PAN-GO

This alone solves ~80% of the problem — users can immediately distinguish tabs.

Phase 2 — User-Editable Title (Search Results Page)

• Ellipsis menu (⋮) in the search results header bar
• Menu contains a "Tab: PAN-GO Results" item showing the current tab name
• Clicking the item opens a rename dialog pre-filled with the current name
• After renaming, both the browser tab title and the menu item text update

Phase 3 — Polish & Future (nice-to-have)

• Persist custom title so it survives page refresh
• Include custom title in export filenames (when export feature is built)
• Add more options to the ellipsis menu as needed

Open Questions

1. Is Phase 1 sufficient? Auto-setting page-specific titles may solve the core problem without needing the editable UI.
2. Scope: Should the editable title also appear on Gene detail pages?
3. Persistence: Should custom titles survive refresh or be ephemeral?
