Repeater Expansion
by iemon1
Repeater Expansion adds a delay value to each redstone repeater and a matching comparator mode, both configurable from the item itself.
What it does
Redstone repeaters gain a longer range of delay settings and can be adjusted directly on the block. The mod also adds repeaters with a chosen delay value to the Creative tab, so a build can start with the exact setting it needs. Comparators receive a similar addition, with a mode option that appears in the Creative tab as its own item.
Holding Ctrl and scrolling the mouse wheel over a repeater changes the delay, and the pick-block key saves that setting to the item in hand. Fabric API is required, and the mod is built for Fabric Loader 0.19.3 or newer. The server and every player need the mod installed. The code is open source under the MIT License, and files are published for 1.20.1 only, with 1.1.0 as the latest file.
Key features
Adjustable repeater delay
Ctrl and the mouse wheel change a repeater's delay, so the setting can be tuned on the block without opening a menu.
Pick-block saves the delay
Using pick-block on a repeater stores its delay on the item, so the same setting can be placed again later.
Creative tab repeaters
Repeaters with a chosen delay value are added to the Creative tab, ready to place at the required timing.
Comparator modes
Comparators get a similar mode option, with variants added to the Creative tab for quick placement.

Use cases
Timed circuits
Builders who need an exact redstone delay can place a repeater with the value already set rather than counting clicks on each block.
Copying a build
A repeater's delay can be saved with pick-block and placed again, which helps when a circuit uses the same timing in several spots.
Who it’s for: Players who build redstone circuits in 1.20.1 and want finer control over repeater and comparator timing. Both sides need the mod, so it suits single-player worlds and servers alike.
