I'm not sure how/when/why but I've got a bunch of old Favorites in my Edge Insider favorites list. I think they came over from Edge10. That said, we need a better way to bulk-manage favorites. Today, I have to right click and choose "delete" on each and every folder I want to get rid of. One. At. A. Time. This is extremely arduous and time-consuming. I long for the day when Favorites were discoverable in Windows Explorer and I could manage them just like files/folders elsewhere on my system. Is there no way to do this in Edge Insider?
I see now the bulk operations must take place on the right-hand side of the UI, which does include folders in the listing. This helps but doesn't necessarily enable all scenarios which a true Explorer-like interface would (e.g. deleting folders/bookmarks inside and outside of other folders in one operation). Thanks for the tip!
