Is there a way to get multi tab bash windows for the linux subsystem in win 10? something like conemu or Multi-Tab putty or console (http://sourceforge.net/projects/console/)
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:
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
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.
