The Classic Edge has this cool feature that you can enable Tab Preivew (or big tabs). If you activate it, the tab bar becomes bigger and all tabs are shown as thumbnail image of the page.
The Tabs also become bigger in width, so it doesn't show as many tabs simultaniously. It's easer for touch but it also helps, if I want to tidy my tabs, when many of them have been collected over time.
I still miss this feature in New Edge. Along with the other missing touch features makes the New Edge unfitting it's Job as main Browser for Windows.
PS: Also in Classic Edge, even if Tab Preview were off, Tabs had a minimal width and could be scrolled through, if there were too many for the screen. That is also still missing in New Edge. Maybe this is intentional, but it should be still available at option at least.
I talked to one of the Edge product managers at Ignite and he said that there was an experimental tab preview feature in Chromium but it wasn't good enough quality for them to ship. He suggested submitting feedback to help make it a higher priority for them so here I am. This is my biggest UI wish for Chromium Edge. With the old Edge it is so much easier to manage large amount of tabs and find the one you are looking for thanks to that wonderful tab preview feature!
