Ive gone ahead and created a profile to test this out. Moving over the bookmarks was easy enough. Tab Groups are connected to Profiles so those don't move over. Not a big deal, mostly I use those as a bit of a backup of tab groups for a project or something so can always toggle back over to Personal since that can't be deleted to pull those up IF ever needed again and just start new tab groups moving forward with this new profile. I'm also not a fan of how it adds a label for the profile it the top menu bar AND connects it to the Tab Group Icon. You can either live with the label for the profile OR just not have quick access to Tab Groups. Don't love that. As a work around, you CAN use a space to name your profile! So while the toggle is still in my menu bar for the two profiles, at least I don't see the text label. Kind of funny on iOS cause when you toggle at the top, it's just a blank bar. OH, and currently open tabs don't carry over to the new profile as well, so a just a bit of copy and paste to "move" from old profile to new, since I have a coupe tabs I always keep open.
