[Suggestion]Tab stacking like in old Opera Presto

A Former User @leocg

@leocg I will add some video of how it is really working but this pictures are photoshoped by me what I would expect or how I would make/like it. As you can seethere is always stack symbol at the right side of the tab no matter if it collapsed/expanded or active/inactive
That is first picture

And the second one show how would I distinguis stacks from each other and standalone tabs by slightli coloring them for example by color of that stack bar from left of tab stack.

Also you can see the stack should be always size of regular tab and never collapse as small color bar. This have some issue because remembering stacks by just colors is not good by by web icon and description is quite easy and you dont have to expand it just to look at first site.
In my opinion just small bar can save some space but for cost of ergonomics and much more mouse clicks.

As you can see if there is no active tab inside collapsed stack then whole stack will collapse to only tiny color bar. I wonder how can you not know that.

I wonder why developers have so much opposition to way how was the tab stacks done with old Presto core. What is the poin just do it differently and make lots of issues in process? Just make it same and wrap it around new GUI design. Why do you have to invent the wheel again?
All these issues will be gone simple by make it like (or at least similar) as old Presto:

Moving tabs in/out of stacks
Moving whole stacks
Non-intuitive collapse/expand stacks by different buttons and possition due to changing size of stack
Hard to recognize stacks and what is inside due to just simple color bar
Complicated stack creation without automatic system and lots of unwanted stack without it
Some wired stack behavior randomly moving (and blocking) around the tabs bar

Just look how great it was... just imagine whole thing with new graphic design of course:
