ZTint by Warewolf Technologies

Colours each Zimbra message row to match its tag, so you spot important mail by scanning instead of reading every tag label. Works in both clients, on whatever host your Zimbra runs on. No tracking, no accounts, no servers.

About this extension
ZTint gives every tagged message in Zimbra a soft wash of its tag's colour, so
you can pick out what matters while scanning the list instead of reading each
tag.

It works in both Zimbra clients — the modern client and the classic ZCS one —
and adapts to whichever one you are looking at.

WORKS WITH YOUR ZIMBRA, WHEREVER IT IS

Zimbra is self-hosted, so there is no single address ZTint could ship knowing.
It installs with no site access at all and asks for nothing up front. Open your
Zimbra client, open ZTint, and click "Use this site" — it checks the tab first
and tells you whether a Zimbra client is really there before you grant anything.

If you would rather not think about it, switch on "Find Zimbra on any site".
ZTint then recognises clients by itself and remembers each one it finds. On a
page with no Zimbra client it does nothing at all.

TUNE IT TO YOUR TASTE
  • Tint strength, so the colour is as bold or as subtle as you want
  • A separate strength for the row you are hovering over
  • Leave messages with several tags untinted, if mixed colours are distracting
  • A live preview, so you can see a change before you commit to it
  • An on/off switch, with the toolbar icon showing "off" while it is disabled

BUILT TO STAY OUT OF THE WAY

Tagged rows are tinted; everything else is left exactly as Zimbra drew it. The
selected row keeps Zimbra's own highlight so it stays unambiguous, and the tint
is mixed against the page background rather than a hard-coded white, so it stays
correct in dark mode.

PRIVACY

ZTint collects nothing and sends nothing anywhere. It makes no network requests
of any kind, has no analytics, no accounts and no advertising. Your settings and
your site list are stored locally in your own browser and never leave the
device — the extension does not even use browser sync.

It reads the message list to work out what colour each row should be, and
nothing else. It does not read message bodies, attachments, contacts, calendars
or credentials.
