To help you enjoy this creativity from the community, every month or two I’ll be introducing some of the new extensions that caught my eye. Here are the highlights for this month:

• UWP Tile Generator (great helper for UWP developers)
• Open Bin Folder Extension (nice and simple)
• DocPreview (Preview XML comments)
• JavaScript Snippet Pack (Code snippets for JavaScript developers)
