WIP This is just an idea I'm playing around with. A shortcut box with an expandable tree using collapsing, that finds the shortcuts using subpages.

Usage
Entering outputs a collapsible shortcut box containing both WP:TCG and WP:TCG/ICP. It can handle up to three subpage levels, and I hope that in the future it might also find common subpages between separate inputs. The width and float can be selected with the variables width and float respectively.
