For Insiders the removal of EdgeLegacy will probably help smooth things out in Windows. There really is no reason to continue updating it as all the NewEdge versions have addressed complaints that first appeared when it was first introduced.
Recommendations :
1. If you click on the three dots in upper right hand corner of NewEdge and then Click Settings You will see near the bottom of the middle panel a listing to import your settings from Legacy Edge.
Would suggest doing this prior to next months update that will remove Legacy Edge.
2. Suggest going over the Settings for the New Edge in order to tailor it for any future use. Microsoft has been good about keeping (most) settings for subsequent times you use EdgeNew.
3. Checkout the Help Screens that Microsoft provides when you first install Edge and when you get updates. They can be very helpful in understanding 'where things are' and 'how to accomplish' things easier.
4. In addition to Favorites, Microsoft has something new called 'Collections' . You may find it easier to use for some things compared to Favorites.
5. If you like shortcuts for things at the top of your browser there are options for those like Sharing, Web Capture and more.
6. You can still save shortcuts to Taskbar or Tiles
7. There are many more options to customize your Edge Home screen and make it your own.
8. If you like to try something new. Lookup the 'Flags' option in Edge. In there you can turn on things like Vertical Tabs and more...
