[Feature]: Custom tab colors based on active/inactive state

[nicksonnenberg]

Feature description

I’d love the ability to customize tab colors based on whether a tab is active or inactive.

Problem

Right now, Wave visually distinguishes the active tab from inactive ones using the default theme styling, but I can’t:

Set my own colors for active vs inactive tabs different color rules per profile/workspace.
When I have many tabs open (especially multiple Claude/CLI sessions), it’s easy to lose track of which tab is currently active, and I’d like a stronger visual signal that I can control.

Requested behavior

Allow configuring tab colors/styles for active vs inactive tabs, e.g.:
Active tab: bright accent color (e.g., green or blue)
Inactive tabs: muted/gray
Ideally this is:
User‑configurable in settings or via a theme file
Optionally configurable per profile/workspace (so different projects can have different color schemes)
This would make it much easier to manage many concurrent sessions and reduce mistakes from typing into the wrong tab.
