Here's a cool addition to the latest version of Chrome Dev for Android cool feature of Chrome that can be enabled via a special flag (which Google started turning on for some recently): when you tap on a text field that the browser has saved before in auto-fill, the entry or entries will appear in Android's keyboard auto-complete field instead of the browser itself. This is a really handy feature, because it avoids the problem that sometimes appears when auto-fill entries drop below the keyboard area, causing you to scroll down and tap the entry, then search around for whatever you were doing before.
Chrome's default behavior on the left, with flag enabled on the right.
We've tested this on Android 6.0 and 5.1, and it appears to be active in the newest version of Chrome Dev, 47.0.2526.6. (You can grab it from APK Mirror if the Play Store isn't downloading the latest version for you.) Just be aware, it isn't enabled by default. Chrome, Chrome Beta, and Chrome Dev. In fact, it may be already active by default for some of you (Google likes to A/B test various new additions). If not, you'll have to dive into Chrome's hidden settings menu by going to chrome://flags/#enable-autofill-keyboard-accessory-view. Enable "Autofill suggestions as keyboard accessory view," relaunch Chrome when prompted, and you'll get the above behavior.
