Gloppers!
Gloppers (glob hoppers) is a Minecraft mod that lets you filter your hoppers by renaming them with glob patterns.
The idea comes from LiveOverflow's Minecraft lets play, where these were silently implemented on his server to make his storage system easier to build.

Usage
First, install the mod. This mod is serverside only and will do nothing on the client (unless you're in singleplayer).
Once it's installed, rename a hopper in an anvil, prefixing with an exclamation mark. Add globs matching the IDs of the items you want to filter for, separated by commas.
Some example patterns:
!*_ore- Matches all ores!iron_*- Matches all iron items!totem_of_undying- Matches only the Totem of Undying!*oak*,*cherry*- Matches all oak and cherry wood items
Note that you must use the internal identifier of the items, and not the item's display name (e.g. writable_book instead of Book and Quill). Don't add the namespace (the "minecraft" part).
Advantages over vanilla
- Only materials required to use are iron and wood (no redstone)
- 1x1x1 footprint, compared to the popular 4x3x1 design
- Ability to filter unstackable items
- No junk items required
Usage in storage systems
Gloppers are most useful in storage systems. Instead of requiring redstone circuits that take up space, you can instead just design it like so:

Items will only be sucked up from the top row to the bottom glopper if the pattern is matched.
Notes with mod compatibility
- Lithium conflicts with Gloppers, and you need to turn its hopper optimizations off in
lithium.properties(mixin.block.hopper=false).
