Hi there 
So one of my favorite combination for a starter template is the use of jd’s Material Theme (http://j.d.material.tiddlyspot.com/) and the TiddlyMap’s plugin (https://tiddlymap.org/).
I know that both are, not really up to date, but I mostly struggle with the “Toggle Fullscreen” feature of TiddlyMap and the Material Theme (tmap-widget tmap-fullscreen).
Here is the actual behaviour, when Toggling fullscreen for the widget, it seems that the widget is not displaying properly and Tiddlers are upfront:
You can test it here: https://twtmmd.tiddlyhost.com
I’ve tried to fix with CSS, but I suspect it’s not that simple.
Does anyone know if and how to fix this?
Thanks,
Cheers
