Michael Quinlan wrote in to let us know that Chrome and Chromium web apps no longer merge in Unity’s launcher.

I don’t what what got updated, but I’m using Chrome 19.0.1084.56 on Ubuntu 12.04 and just noticed that my Google Reader (Chrome Application), Google Drive (Chrome Application), and Chrome itself all have arrows indicating that the “app” is active, and I can use the Unity launcher to switch between them.

Prior to Ubuntu 12.04 I was using the classic interface specifically due to the merging icon issue, but have been giving Unity another go since updating to 12.04. I’m glad I did!

To be honest it may have been like this for a while; I stopped using Chrome web apps in Ubuntu a while back because of this issue. Trying to manage 3/4 open web-apps at once was harder when they all hid behind one icon.

But that has now changed, so if you were put off previously it might be time to give it another whirl.
