win 10: linux subsystem multi tab bash

You should be able to use something like MobaXterm and open multiple linux subsystem tabs. Take a look at this article and scroll down a bit to the demonstration video where he opens WSL tabs:

Also, as an aside, there is this UserVoice issue that appears to have been approved but is not implemented yet:

Windows Terminal worked quickly and easily for me: https://www.microsoft.com/en-ca/p/windows-terminal-preview/9n0dx20hk701?activetab=pivot:overviewtab

Something similar you can use is a common linux utility called screen. If not installed by default you can use sudo apt install screen once installed run sudo screen

You can now run the command screen to start a screen emulation, these are like invisible tabs. To create a new tab type: ctrl-"a" "c", to switch between tabs type ctrl-"a" "n"

This basically lets you have concurrent shells running. ctrl-"a" "d" detaches you back to your primary shell.

You can just start a new instance of WSL instance of the same thing (eg: Start > Ubuntu ) and it will open up a new terminal (separate window) which operates on the same linux file system. It is simple although not another "Tab" but it should get your problem solved.

I use vi to edit files while I browse using other terminal window.
