Lovely Addon, though it would be neat if the HOPIUM Syringe could be placed in the Others category instead of it having its own Weapon/SWEP category.

For a more in-depth reasoning...
...This item is just a single SWEP, and unfortunately the Weapons tab gets cluttered when every small, yet neat Addon creates its own new category.

From my perspective, the others category has more than plenty of space for awesome SWEPs such as these, so in my opinion moving it there would keep the Weapons Tab Spawn List more organized.

Kind Regards.
