When picking a block in survival the mod will first search through all the items in your inventory. If it can't find the item, it'll search containers like shulkers and bundles that are inside the inventory. If found, the mod will move the container with the highest amount of that item to the player's main hand. This should work with all item-containers that work in the same way as the shulker or bundle do.

You might already know it's possible to hold CTRL while block picking to copy block-entity data, such as player skulls and banners with patterns. This mod allows on top of that to also copy block-state data when holding ALT, this includes for example if a campfire/candle is lit or not and also the rotation of blocks like stairs. (There are many more things you can copy with this, see wiki link for the full list) 
This feature was inspired by the Pick-BlockState mod by Minenash.

Just like how you can pick block-entity data, now you can also pick entity data. This will for example copy most data of the mob and put it inside the spawn egg as NBT data. This will also work for things like armor stands, item frames (copying what's inside of them) and paintings (copying the exact variant of the painting).

By default Minecraft only allows to pick blocks that are within reaching distance (3 blocks). This mod however allows to pick blocks at a distance of 100 blocks away and this can even be set way higher (or lower) if so desired. No need anymore to fly all the way over to a block you'd like to pick.

Pick Block Pro comes with an overrides.json config file. Within this file you can configure which item you should get when picking a block or entity. This also has full support for NBT data.
The file already includes some overrides for blocks and entities that didn't have any pick stack.

The overrides can be reloaded in game with the command: /pbp reload

Default overrides:

{
    "Block to ItemStack": {
        "minecraft:fire": "minecraft:flint_and_steel",
        "minecraft:soul_fire": "minecraft:flint_and_steel",
        "minecraft:frosted_ice": "minecraft:ice"
    },
    "Entity to ItemStack": {
        "minecraft:tnt": "minecraft:tnt",
        "minecraft:fireball": "minecraft:fire_charge",
        "minecraft:wither": "minecraft:wither_spawn_egg",
        "minecraft:ender_dragon": "minecraft:ender_dragon_spawn_egg",
        "minecraft:giant": "minecraft:zombie_spawn_egg{EntityTag:{id:giant,CustomName:''},display:{Name:'{\"text\":\"Giant Spawn Egg\",\"color\":\"light_purple\",\"italic\":\"false\"}'}}",
        "minecraft:illusioner": "minecraft:evoker_spawn_egg{EntityTag:{id:illusioner,CustomName:''},display:{Name:'{\"text\":\"Illusioner Spawn Egg\",\"color\":\"light_purple\",\"italic\":\"false\"}'}}"
    }
}

By default Minecraft will first fill in all empty slots in the hotbar when using pick block, however once the hotbar is completely full it'll replace the item in your current selected slot. This item might actually be something you'd prefer to keep. This mod lets you lock any slots you'd like in the config settings. When locked, this mod will still place an item inside that slot if it's empty. However once an item/block is located in a locked slot, this mod will skip that slot (keeping the item/block safe) and use the next available slot instead.

When using the Tool Picker this mod will provide you with the best tool for the job. In creative you'll get a fully enchanted tool (configurable), but in survival it'll go through your inventory and search for the best tool instead. If it's able to find a suitable tool it'll switch it to your current selected slot.

Copy the ID's of blocks/items from your hotbar directly in the chat when it's open. Making it a lot easier and faster to create WE commands. Especially great for making brushes with a lot of different blocks. Hold CTRL + 0 through 9 while your chat is open, 0 is for the off hand slot.

Ever wrote a WE command using block ID's with a lot of properties? This mod will make that a lot easier by allowing you to pick the ID including properties of the block you're looking at directly into your clipboard. Once picked you can then paste this ID when writing out your command.

When using the ID picker it's also possible to copy (block)entity data to the clipboard by holding CTRL.
