At the moment i see that split window has the priority over tabs but i would like to have the opposite.
I explain.
Now i can split the panel in 2 (i use vertical) but then i have separate tabs for each of thiese 2 tabs.
I would like to have a tab with full panel together with another tab that has split panels
You don't have to do it every time, you can save the tabs in that state. Or you could make a button which opens a new tab on both sides and links the two new tabs together, etc.
In terms of what you're asking for, Tab Groups are the closest thing to that. Or buttons which change the folders on both sides at once.
Tab groups? no....for what i see this is to save the tabs i want to be active but that is not important. the 2 tabs i showed in the picture are just random.
I need this when i have to keep opened a folder with many many files (that's why i need full panel) and at the same time another tab with split view.
