I suggest
Add a velocity setting to SpeedHack and allow player to enable/disable autosprint,minijump and speed limit(for NoCheat+).
Make KillPotion able to kill undead mobs.
Make TrollPotion able to select Buff and Debuff.
The custom name of KillPotion and TrollPotion had better be able to disable,for some servers may detect and ban it.
Make Search able to search only exposed blocks,because some anti-xray plugin on some server may generate fake block but exposed blocks are usually true block.
I have done these suggested change in https://github.com/xbound/better-wurst .I hope these changes can enter the official version.
