Yup! The cool thing about Tiddlywiki is that because it's one massive blob that executes clientside, and because it's designed to be extensible, you can yank the plugin Stroll uses right out of Stroll. If you go to https://giffmex.org/stroll/stroll.html and click plugins on the sidebar, you can see a list of installed plugins; Stories is what he's using to get the second column, and it shows up with this link: https://giffmex.org/stroll/stroll.html#%24%3A%2Fplugins%2Fsq...
Click and drag that to the tab with your own TW open, and you're good to go!
I haven't used that plugin so I don't know if it's good or whatnot, but there you are.
