IE11 supports dragging files from the desktop/File Explorer to upload to for example OneDrive or other sites which use the HTML5 file upload API and support drag and drop.
This doesn't work in Edge. This is a quite serious regression.540 votes

Please UPDATE your WebDriver module for Edge and support XPATH and other missing identifier functions, etc., so we can run the same scripts to test Edge in the same way we test other browsers. You say you are going to support it, but if you don't update it, that's not supporting it.12 votes
WebDriver was updated with the November update of Microsoft Edge. You can view https://dev.windows.com/en-us/microsoft-edge/platform/status/webdriver/details/ to see details of our WebDriver support.

webkit currently supports the property background-clip: text that can be used to create awesome text filled in using background images, gradients, ect. Its an incredible feature with so many possibilities and I'd like to see supported in other browsers.3 votes
The non-standard -webkit-background-clip: text; is already supported in Microsoft Edge due to interoperability issues.

These basic form validation types is still not supported on IE, even on Edge, whereas they are supported by competing browsers like Firefox and Chrome.
<input type='text' pattern='[input your validation here]' />
<input type='text' required />
That will be very useful as we don't need to use server-side coding and even JS coding.84 votes
The required and pattern attributes are supported in Microsoft Edge

Preload is included in EdgeHTML 17 released today (30/04/2018)
would be nice to use that feature, IE seems to be the only browser without support for it :)2,067 votes
The form attribute is included in Edge 16
element.runtimeStyle is non-standard, unnecessary and unintuitive.
- It doesn't match any standard or any other browser.
- We already have the `style` attribute on elements.
- If I clone elements with any runtimeStyles set then the clones also get the runtimeStyles. But if I copy the elements using an `.innerHTML` (or similar) approach then the runtimeStyle is not copied.6 votes
element.runtimeStyle was removed in Edge.
Implement extended srcset which includes support for the sizes attribute on the image tag and the addition of the width descriptor instead of just the pixel density descriptor inside of the srcset attribute.151 votes

Edge should prevent a page from repeatedly popping up modal dialogs that block action on the current or other tabs. In IE 11, it is possible for a page to pop up a modal OS dialog window, and upon attempting to close that window, simply re-open it. I experienced this today with a rogue fake virus warning page, and had to kill the entire IE process to get rid of the dialog. Simply unacceptable from a security standpoint.114 votes
I used to use the el.createTextSelection method to determine the selection direction in IE11. However, inputs and textareas no longer expose this method, while still the el.selectionDirection = undefined.
We don't have any way to determine selectionDirection now.52 votes
the selectionDirection property for input elements shipped in EdgeHTML 13 as part of the Microsoft Edge version included in Windows 10 build 10586 (November 2015).
