As evidence of those capabilities, she cited integration between Universal Windows Platform (UWP) apps and extensions, improved (and more) APIs (application programming interfaces) opened to developers, and add-on access to the browser's bookmarks. 'Before we could enable a wider ecosystem of extensions for our customers, we needed to improve the capabilities of our extensions platform to allow new categories of extensions and more features for existing extensions,' Williams said. Williams touted the headway the company had made in convincing third-party developers to craft browser extensions, and more importantly, she said, in building the foundation that will allow more capable add-ons down the line. 'We are excited to share a few updates on the progress we have made since then.' 'It has been a little more than a year since Microsoft first shipped the number one requested feature for Microsoft Edge - extensions,' wrote Colleen Williams, a senior program manager with the Edge team, in a post to a company blog.
