Back at I/O, Google previewed a few new items in Chrome. More specifically, it detailed a tool called custom tabs. Basically, it'll allow app developers employ a pop-out browser window for link previews inside their apps instead of booting you elsewhere (see an example after the break). Those custom tabs are part of the Chrome Beta 45 for Android that arrived this week at Google Play. What's more, the in-app browser of sorts also keeps all of your saved info from Chrome handy (log-ins, etc.) so that you don't keep typing them in. The beta also includes updated media playback controls and Bookmarks interface. You can nab the software via the source link below if you're itchin' for access before the official release.
