Google Inbox has a new attachment picker. When you compose a new message and click the paperclip icon, Google now shows a list of recently received attachments, a list of recently sent attachments and the latest photos uploaded to Google Photos. Click "show more" to see the rest of the attachments and photos. You can also select files from your computer. Unfortunately, there's no Google Drive integration yet.
"Inbox by Gmail on the web now makes it easier to share memories with instant access to recent photos and attachments," informs Google.
