New web platform features

• Drag and drop folders: Users can now upload folders to sites like OneDrive, Dropbox, and Google Drive by dragging and dropping into Microsoft Edge.
• Better tab behavior on Mobile: Microsoft Edge keeps your tabs under control when you use it with apps on your phone. If you tap on a link in an app that opens a new tab in Microsoft Edge, pressing the back button when you’re done will close that tab, then take you back to the app. Your tabs list stays lean and relevant, by smartly closing tabs you’re done with.
• Better copy/paste on Mobile: We’ve made a couple of improvements to copy and paste on the phone. When you are typing into an edit box on a web page, you will now be able to use the paste button above the keyboard. Also, if you select text on a web page the copy button will appear immediately near the selection.
• Better favorites importing: You can now import favorites from Firefox, in addition to Chrome and Internet Explorer. When you import favorites from any browser, they will now land in a separate clearly labeled folder, instead of mixed in with your existing favorites.
• Favorites tree view: Organizing your favorites is now easier using the new “tree” display in the Hub. You can expand and collapse folders to see the contents of as many or few as you like, and easily move favorites between folders with drag and drop.
• Download reminders: Edge now gives you a reminder of in-progress downloads whenever you close Edge. This gives you the opportunity to complete downloads prior to closing Edge.
• Default save location: You can now set where downloaded files are saved by default. Just open “Settings”, choose “Advanced settings”, and find the new option under “Downloads.”
