I love the bundle plugin (even used to contribute to it). It's strange that it's not displayed in the Joplin plugin store, because it used to be. Could it be that its manifest needs an update @personalizedrefriger?
I just re-built the plugin in a separate fork, so anyone can download the jpl and install it on desktop or mobile. It doesn't work on mobile because of dependencies that are not available (it will probably also need some modifications).
However, until it's migrated to the mobile app, if you're interested in displaying TODOs in a panel I recommend checking (disclaimer: my) Inline Tag Navigator plugin, which is supported on mobile. There are simple instructions how to set it up to display inline TODOs. You may use it to filter them and toggle checkboxes.
