Chrome Custom Tabs is a pretty unique feature, and one that we're seeing more and more apps take advantage of lately. It saves developers a lot of work actually. Instead of needing to build in a bare-bones browser to their app - or send users out of their app to Chrome or their default browser - developers can use custom tabs from Chrome right inside their app. Twitter is actually using it in their official app and so is Facebook. Now Google+ have added the feature to the latest version of Google+, which is version 7.0 and it started rolling out last week.
The code was there in the latest version of Google+, but it appears to be going live in a server-side switch. So while we all might have the latest version of Google+, it's not quite live just yet. But it should be pretty soon. For most, you may not notice a difference. But what happens here is, instead of being taken out of the Google+ app and into Chrome (or again, your default browser on your device), the page opens up within the Google+ app in a Chrome Custom Tab. It makes for a much nicer user experience, and in the overflow tab, you can choose to open up the link in Chrome or your default browser.
Google+, while many think it's the forgotten child of Google, is still getting updates. Even with its recently rolled out new user interface, it's getting updates quite often now. Both on desktop and mobile. It's great to see updates like this coming into Google+, as it makes the app a bit more user friendly, and easier to use. Google+ also recently got a whole lot smaller in size. So those with not a whole lot of storage left on their smartphones, can still use Google+ - and it's no longer pre-installed on newer smartphones. The Chrome Custom Tabs feature is not yet available for us - as we mentioned it is a server-side switch - and the image above is from Twitter, which also uses Chrome's Custom Tabs. We should all have it in the coming days though.
