New
- You can now remove GenStepDefs. GenStepDefs are steps taken by the map generator. For example if you remove GenStepDef/AnimaTrees, it will remove anima tree generation, which is more reliable than trying to remove the anima tree def itself. (For this particular example you may also want to remove the anima tree respawn event too).
- Improved error logging.

New
- You can now remove PawnKindDefs, great for removing certain types of enemies like for example PawnKindDef/Grenadier_Smoke which is wholly useless and doesn't even have AI to use its weapons!

Hotfix: the 2nd Dec 15 update, regarding mod extension removal, has been reverted and replaced with a white list system for now.

Update
- Kill leavings now respect removed defs (special instructions for things to drop when something is destroyed, as opposed to deconstructed)
- Comp spawners now respect removed def too (for example the insect hive is a comp spawner that spawns jelly)
- Some big changes in how def removal is processed under the hood. Before, each time a def was processed, it would first edit that def itself, and then sift through the database looking for other defs that reference this def. That means the database was crawled each time for each def removal. Now, it only does that second part one time for everything at once.

The drug policy management UI now respected removed drug defs. However, this only applies to newly created drug policies because existing policies are baked into your save data.

You can now remove corpses. Doing so only removes them from the filters and ingredients, though.

Removed defs are now stripped of their mod extensions, which should help with a few special mods like Seeds Please, for example.

Improvements to weapon, plant, and implant removal.

Fixes a bug where backstory removal was not persisting between game reloads.

New
- DefLists: DefLists are a new type of def added by this mod. They simply contain a list of defs. Other modders can create DefLists for their mods to create premade lists of defs.

For example if a mod author wanted to allow users to remove chunk of content from their mod as a convenience, they could create this list, and it would show up in the Cherry Picker list.

In the future, this same mechanic will be used to allow users to import/export their own cherry picked lists.
