I'd strongly prefer if plugins use the same capitalization we use upstream for Fisher, not fisher.
I'd much prefer Fish over fish or fish-shell, but I didn't touch any of that here as you might reasonably consider that opinionated and there's nothing wrong with your current choice either.
Because Fisher installs plugins concurrently, a one-liner is more idiomatic, and faster. ✌️
Here's another PR! 😅
fisher.
