Worskpaces/Containers feature feedback

I know this a bit of a essay I am going to write below and my feedback could be all over the place, but I would like to express my vague idea and some issues i faced when using a browser which had workspaces. I also attached a small rough sketch i made just now to explain how i think a rough visualisation of workspaces could be at the end of response

*** What do you like or dislike about the Workspaces/Multi-account containers/Profiles features you’ve used in other browsers?**

What I like: workspaces implementation is useful in academic/project setting to seperate concerns. I like the heirarchy of the workspaces implementation Arc has. You have different profiles(kind of like in Brave) and each and every workspace is assosiated with a profile. So, multiple workspaces can have synced passwords etc., while having the bookmarks, favourites seperated. I can simply have an profile with all my school related password and accounts and then have multiple workspaces in each profile for specific subject or project.(You can translate the analogy to any field) You can then have other profiles for other tasks.
To put it simply: You can see workspaces and use them but the profiles tie some of them in the background.
What I dont like: It is impossible in some browsers(ahem Arc) to export all your bookmarks/favourites and passwords when changing browsers. I suffered a lot when switching to Brave. Please if possible think of a clean way to integrate the workspaces to export functionality.

*** Why doesn’t the profile functionality work for you? You can have multiple profiles, each working as a clean slate for the browser in the practical sense.**
As I said above it is great that profiles offers a clean slate, but in most cases it is better to have a state based on a profile in the background. Like if i want to create a new workspace for my new project, I can simply create a new workspace for the project with the Work Profile. I would still have most of my passowrds, base settings in place. I can then set a differnt theme(identify quickly which workspace i am in) and then add project specific bookmarks, favourites, account logins etc.,
*** What kind of information do you want to keep separate between these “spaces” (e.g., Browse history, cookies, logins, extensions, themes)?**
As said above i would like to have base settings of profiles like password info, extensions to be shared across the workspaces within each profile. But, i would like the logins and browse history, favorites and bookmarks to be separate across them.
*** When separating different logins/sessions, is having them visible and accessible within the same browsing window important to you?***
Yes, i would atleast like to see a small icon/visual indicator to identify quickly which workspace i am in and a keybinding option in settings to switch between workspaces.
*** Are there any specific websites or web applications that you would always want to open in a particular “space” automatically?**
we can implement pinned tabs/tab groups in workspace to always open automically when switched to that workspace.
