As said by @jinsight, if you want multiple rows of tab, it can't be done.
I did have that kind of issues from time to time in my listers, and the solution I came up with was to organize my frequent tabs in tab groups and I made a FAYT script to be able to open or close those groups "on demand".
This requires your issue comes with frequently used tabs (e.g. folders required by some of your workflows) not just random folders you happen to open for specific "one-time" situations.
Another option is to build several listers layouts with smaller number of tabs, each one dedicated to specific workflows. You can then open the lister that suits your activity.
FWIW, the FAYT script to open/close the tab groups :
And a button to list all open listers with their creation layout name (to bring it to front) and a script add-in with a command to Activate (if existing) or Create a lister based on a layout name :
