And like I said before this is a place to ask for new features...

That has nothing to do with the profile for each Space.

When you create a new profile to use in Space it create a full new Chrome profile... so inside Arc userdata you have that:

Default (the default profile it comes)
Profile 1 (the first profile you create)
Profile 2 (the second one)
...
Profile N

This is a default Chromium profile folder... that is what is used to different profiles in each Space.

The files there are 99% similar in name to what you found in Opera profile folders... there is some files different but Opera has some of them too.

Arc is not doing something magical... it is just linking a Chromium profile to one Space... just imagine Spaces as being like another window in Opera (with it own profile) but displayed as a workspace instead window.

When you shift Space everything shift with the data of the other profile... folders, pinned tabs, cookies, bookmarks, etc... the StorableSidebar.json probably holds the configuration of the Spaces and the profiles linked... not the info of what is inside the Space / profile (that data is probably inside each profile folder like Opera has a folder for each profile and display the windows with the data of that profile folder).

See here the Arc data folder: https://i.ibb.co/sj7h9Z6/image-2024-08-26-154538664.png

They probably could even link a profile to a Tab if they wished but I think that should create a mess in terms of organization... linking profiles to Workspace is how Workspace should always work since start.

About demand... I guess there is market for that... at least a bigger market than Opera markeshare because Workspace doesn't make sense at all without different session / profiles... the market share of Opera today is very small... any gain is good.

It seems to use one of those files, StorableSidebar.json, to store information for spaces, such as space names, folders, pinned tabs, etc.

But the Workspace part works on Windows for these that wants to see how it is.

You can assign a different profile to any Workspace, and change it anytime you want... and you can change between Workspaces just like you do in Opera... it is ver snap without any delay at all.

In fact the Workspace is very similar to Opera... the difference is that you can use different profiles that is basically what we are asking to Opera add.

UI side Opera is way better than Arc... and that is even more evident in Windows.

I won't talk about others browser not based in Chromium because I think we should focus in what Opera is based... so I only know Arc that does Workspace with different profiles.

And yes you can do in the same windows... you change anytime the Profile used by an Workspace... it doesn't open a new browser windows and you can have several Workspace with several different profiles.
Not sure how it does internally but it works pretty well.

The browser works as a sidebar like Opera... the difference is that there is no other option it is all in the sidebar (it only has vertical tabs not horizontal)... the Workspace and sidebar part is very similar to how Opera do it.

Said that Arc on Windows is not good... the UI is bad and lacks some key features.... on Mac it is pretty great.

My point was it is not impossible because we already have somebody that did it... and as a consumer it is not up to me to realize how it works... maybe Opera engineers can understand better how it works and how to do it even better.

1. Virtual Desktops
2. Development Environments

Sounds like a neat feature at least. I would guess it'd be a lot of work to do in Opera though. Maybe some of the guest tabs work in Opera GX would help as a foundation.

Couldn't find out how Arc change from a profile to another when the user changes to a space that uses a different profile.

Based on what what I read on their page, their workspaces seems more of an (sidebar) extension.

That has nothing to do with Chromium... it was about Opera.
Before that excuse was used here but today we have Chromium browsers with Workspace that have different profiles.

Explain to me how can The Browser Company can do it and Opera not?

Workspaces, as said, it's just a way to have tabs grouped and separated by category,nothing more than that.

You can't have workspace with different profiles in Opera... that is why we have this feature request thread.

I don't know how people use their browsers... but I have one browser for Work and another browser for Personal because the authentications in the sites are different (aka my Work profile should be different from my Personal profile)... when I say one browser it means one of instance of any browser running with a profile (so it can be two Operas).

The best way to organize that is to have one workspace for Work, one workspace for Personal and even have options to have others workspaces like University for example.
But without profiles / session per workspace it will never works... so it become useless to use Workspaces because in the actual state of Opera you will need to have two Windows opened.

Workspace is suppose to allow you to have grup of tabs without need to have another windows (browser instance)... but not having profiles / sessions kills it purpose.

In simple terms if I already have to open two, three, etc browsers to deal with different "working subjects" then why I need workspaces at all? Unless these workspaces allow to have different "working subjects" wihtout need a new windows / browser opened it will be useless and redundant.

PS. It become even more trick if you work with several clients... so for example the Salesforce authentication for one client is different from others clients... in that case you could have one workspace per client but how Opera works you need to have one browser window (instance of opera) per client.

I have no ideia how when we ask for workspaces with different profiles some here understand that we want just different profiles lol

Like I said if I need a new window to have different profiles then it will be same as having several browsers... it doesn't organize anything at all.

In Opera GX you can create profiles.
