In old Internet Explorer and also in Chrome, the Tab Groups (TG) features is a way to stack tabs together in a color-coded with manner with an optional title.
Edge Collections is a semi-tab-groups behavior, that lacks most of the TG functionality.
Here's how I'd like to see this integration happening:
When clicking or Ctrl+clicking a link on a page, add the opened tab to the same TG as the source, creating a new group if necessary
When pressing Ctrl+T, the new tab should be in the current TG
Allow saving a TG for later use (via Collections)
Allow pinning or closing of a TG as a Collection, so it gets collapsed for later
Enable "Open all tabs" in a Collection - and it should be opened as a TG
Allow closing TG with a single click
Collection and TG should be under the same definition and should be seamlessly managed together
All actions should be able to be performed from the tab context menu
Tab Groups should be available in Desktop and Mobile versions of Edge, like Chrome. This is a deal breaker to me, it's functionality I got used to, and when using Chrome on Mobile I can't share links via "send to device"
@Shimmy Weitzhandler Thanks for the detailed feedback! We have some good news: you can now enable Tab Grouping within Microsoft Edge. Paste the flag edge://flags/#tab-groups into your browser, ensure that Tab Grouping is listed as "enabled," then restart Microsoft Edge.
For the Collections-specific feedback, you can submit that through the in-browser feedback (Shift+Alt+I), so that we can direct it to the right team.
