Edge itself is a type of "breakdown" in the light of what it will not enable. See post 20. But if all you do is open just a few tabs (versus hundreds across 5+ browsers) and then I can how that could suffice.
Why would you open hundreds of Tabs at the same time?
I keep all my Edge links (well over 100) perfectly organized behind the Favorites icon - zero Tab chaos on my screen.
Edge does have side stacked vertical rows of regular sized tabs on the left side of the screen. They recede out of sight when you pull the cursor away.
The first thing I notice in Comment #20 is that there is no horizontal Open Windows bar at the top of the page - is that hidden? Is that even being used?
#20 says Edge cannot close a window by clicking the X?
I can click the X directly in the Windows bar, or in the specific Window, or in the mini-image that displays from the Edge icon at the bottom of the screen - closes every time.
Cannot toggle? I can toggle - but it is faster to just click the window you want.
Spell check has many options - just start or stop them with your preferences in Settings.
Edge Dictionary? I like a full service dictionary, and I keep one open
Cannot right click Copy Link in tabs?
Put the cursor in the address bar - works fine.
Find/Search icon will not stay open across tabs?
Just minimize Search page, open the new Window, maximize Search page, you are back in business with all your info saved.
I will close were I started - with the Edge Copy Image command not working.
When that first came out in Edge, it allowed you to copy and post copyrighted photos and graphics in Free Republic.
I think it is possible that Microsoft disabled it on purpose.
But, I did find an Edge work around for non-copyright images, so it is not a big issue.
