Not sure if this is new or not but there is some new iconography in Gmail for the web. I use the web version of Gmail daily and haven't noticed this change until this afternoon. The new-look pretty much matches what's available on the Android app. This may be an A/B test or server-side push so don't fret if you don't have it yet. Have a good weekend folks!
