Within the workspace work, you can have groups of tabs such as search, news, tools... each with a different name and color for easy viewing.

It would be interesting to have this feature native to Opera or some good extension that implements this feature. Worskspace with Tab Group would be awesome!

And there should be a setting to use two or three rows for the tab bar. Plenty of room on a lot of monitors to do it.

The code is presumably public and all that needs to happen is to adapt it to Opera's style.

Even with workspaces, it's still handy to have (sub)grouping. I literally have a dozen or more contexts of tabs. I don't want a dozen workspaces. I want to subdivide workspaces into groups of tabs occasionally.

I normally work on multiple tasks at the same time, so I use the workspace to manage them in priority. However, I also want to group all tabs that belong to a single task, so that I can easily see how many steps I have done for the task, and how many tasks are included in the current priority workspace.

There's not even a right click function to add an open tab to a workspace. So I open it up in the new workspace, or try and drag it over, which is a pain.

When workspaces are enabled, a tab is always in some workspace. So, if you want the tab in another workspace, you right-click the tab, goto "move tab to workspace", and choose the workspace you want to move it to.

Or, are you saying you want to right-click a tab and have a "Create new workspace and move this tab to it" option?

Also, when I click on a workspace in another window, it's empty. Yet each workspace appears to be a new browser window.

Workspaces are a visual thing. The tabs from all workspaces in a window are still technically together on the same tab bar and are all from the same window they're in. When you open a new window, just like if you had workspaces turned off, you get a blank slate of tabs that's separate from other windows. So, since each window has its own tabs, the workspaces in each window only show tabs from their window. There's no sharing between windows as far as the collection of tabs in each workspace goes.

Yes always looking at different browsers. Vivaldi does have a nice appearance modiier. But that in a minor thing. The workplaces in Opera are great.

But they completely lack a decent workplace interface which is what I love about Opera.

The other one is tab gathering, which I think most programs have, so I needn't clarify how valuable they are.

By the way, couldn't you just use several windows in your Work workspace, instead of creating several workspaces?

I will say though, we should try to stick to one request per thread. Stacks and groups can be considered the same request, tiling tabs and splitting the window is a separate request and deserves its own thread

So to summarize, the argument for stacking or grouping as opposed to workspaces is that stacking doesn't hide your other tabs, and that some extensions allow you to group related tabs automatically. Anything else?

Right now for example, I have 2 pinned tabs (Google Drive and Gmail) and 6 different (but all work-related, so all in the "Work" Workspace) sets of Spreadsheets and Code open right now. These sets change pretty much everyday, for me. I would love to be able to separate them into quick groups, both so I can read the name of the files better and so I don't mix up which Spreadsheet tab is which, since they all have the same Google Sheets logo on them. But without groups, I can't do that.

If I went for a Workspaces approach to this, I would have to create 6 different Workspaces each with about 3 tabs open, all of which would be work-related and only relevant to this work-session (thus I would have to delete those Workspaces later, since they'd lose relevancy), and also missing my pinned tabs. Once again, Workspaces are very useful, but they are more akin to having multiple browser windows open at the same time than what tab grouping provides.

Is there any place to officially provide feedback/feature suggestions to Opera? I'd appreciate if you could link that here, or otherwise pass the suggestion onwards to the appropriate team, if you have access to that.

There is a flag to enable drag and drop to move a tab to another workspace, It's something still in implementation.

1. AFAIK, it only allows up to 5 workspaces.
2. Drag and Drop is not supported to move a tab to a workspace. I mean Right click > move to workspace is fine, but once you're used to drag and drop, you kinda expect to be able to use it whenever possible.
3. Personally, I use workspaces to separate between personal / work stuff. For example: I have Facebook, Youtube, Instagram... on Personal workspace; Github, Stackoverflow, Jira... on Work workspace. And I want to group tabs that are related to each other within my Work workspace. For example, I'm working on several Jira tickets at the same time, then it's something like this in Chrome:
   

I second this feature request. It would be really useful. An implementation such as the one found here would be very nice:

Unfortunately that particular extension does not work on Opera GX so it would be greatly appreciated if it were to be natively implemented in Opera GX.
Essentially what the extension does is group the tabs by domain so say you have 7 different youtube tabs open. Firstly all 7 tabs would be grouped together in the top most tab selector in a tab called Youtube afterwards, once you click on it, a 2nd tab selector appears below the top one where u can select which one of the 7 tabs u wanna look at. It basically creates a top most main tab selector and a secondary tab selector below the top one for the tab currently selected.

Unfortunately I'm unable to edit my last post but this is how the extension looks in Vivaldi. Sorry for the double reply.
