Fixable Slots [Forge(1.12.x)/Fabric(1.16.5 & 1.17 )]

With the help of Fixable Slots, your loved items or blocks are at their right places every time.
Fixable Slots adds the ability to lock your player inventory slots, including hotbar, so that only the stated items can go in there.

There are several filter, to keep it as practical as possible.
1. Exact mode: Only the given item can go in there. It is meta/damage and NBT locked
2. Fuzzy meta mode: All items with the same id and same NBT can go in there. The meta/damage is ignored (eg: For tools).

3. Fuzzy NBT mods: All items with the same id and same meta/damage cana go in there. The NBT hasn't to be the same (eg: For forestry bees)

4. Fuzzy strict: All items with the same id can go in there. NBT and meta/damage are ignored completly.

5. Tag mode: All items with the same tag as applied can fit in the slot. The applied tag cycles through when you try to change the slot type.

To lock a slot to a specific item, just drag the itemstack and click the scroll button while hovering over the intended slot. You can change the filter by clicking multiple times.
