QuasiDusting
QuasiDusting changes how redstone dust feeds quasi-connectivity, letting players choose which faces of a block the dust can power.
What it does
Quasi-connectivity lets a block be powered through a neighbor that is diagonal to it. QuasiDusting makes this behavior directional and toggleable with redstone: right-clicking a quasi-connectivity affected block with redstone dust in hand marks the face that should respond. Only the faces where dust has been applied take part in the effect, so a lever can drive a piston dropper while a sticky piston next to it stays inactive.
Shift-right-clicking places redstone dust as usual and leaves the block's quasi-connectivity state untouched. The mod is a Fabric mod that needs Fabric API, and it runs on client and server, so the server and every player need it. Files are published for 1.21 – 1.21.4 under the Creative Commons Attribution 4.0 license, and the mod is not open source, though its source code and issue tracker are public.
Key features
Directional quasi-connectivity
Each face of a quasi-connectivity affected block can be set to respond or ignore the effect, through a right click with dust.
Placing dust normally
Shift-right-clicking places redstone dust without changing the quasi-connectivity state of the block underneath.
Controlled redstone signals
Signals only reach the faces that were marked, which keeps unrelated blocks next to a contraption from switching.
Compact contraptions
Directional control lets builders make denser and more varied redstone designs with fewer workarounds.

Use cases
Piston droppers
A lever can drive a piston dropper while a nearby sticky piston is left inactive, because only the marked faces respond.
Who it’s for: Redstone builders who want quasi-connectivity to behave predictably on specific faces, and server owners who run redstone-heavy builds.
How it compares
Redstone++ is a Fabric mod for 1.21.10 – 1.21.11, licensed under the MIT License and open source. Smart Placement is also Fabric and open source under the MIT License, covering 1.21 – 1.21.11, but it is client-side only, so servers run without it. Quick Redstone is server-side only and targets 1.21.1 – 1.21.11 under the MIT License, not open source. RedTooth is server required with the client optional, for 1.21.6 – 1.21.7, under CC0 1.0 Universal.

What the author says
This Fabric mod modifies Minecraft's quasi-connectivity (QC) behavior, making it directional and toggleable by using redstone on a QC affected block. Using this, you can control which faces of QC-affected blocks are influenced by redstone signals a block away! A variety of examples: The piston and dropper are active…
