💗 🔶 👦🏻 Plugin Strategi Moksi 🏳️ 👶🏿 🙅🏻

Terkadang hal-hal sederhana sangat melelahkan, terutama ketika mereka harus dilakukan terus-menerus. Salah satu hal ini ketika bekerja dengan kerangka Moxy adalah menambahkan strategi ke fungsi. Untuk mempercepat proses ini, sebuah plugin ditulis , yang oleh "alt + enter", memberikan pilihan strategi jika tidak ada atau dialog dengan pengganti untuk strategi lain. Mereka yang ingin tahu cara kerjanya, selamat datang di kucing.
