Folders available for tabs
Creating tabs within tabs. Allowing tabs to be joined and creating a larger tab to put files and other needed tabs within it.
Similar to OneNote

I agree on this.
I came to suggest an option to show the tabs in a tree-like structure to the left of the content.
Being able to organize tabs in folders and having a menu that would allow easy navigation would open up for improved organization of information in a channel.
