Modding
PineDebug, since it's release, can have brand new buttons from other mods, starting with B. Carnell's Plus Pack! As long as PineDebug is a soft BepInDependency for the mod that has PineDebug support.
With it's following example code:
It does simply work, all it does is that it inserts a new button to the Stupid Casualties page and also adds in a new delegate for the /kill e button in order to properly destroy Mr. Portal Man's spawned output portals.
There is no need of patching the PineDebug manager itself (unless that said feature is unavailable) so add in PineDebug support if you need to.
