Hi @zep, I still feel like a noob at Japanese so maybe I'm missing something but shouldn't
"lya", "lyu", "lyo" produce ャ,ュ,ョ in the Katakana mode?

In hiragana and Katakana input modes they both make ゃ,ゅ,ょ.
Thanks in advance.

The input I am accustomed to is "xya:ゃ, xyu:ゅ xyo:ょ".
Therefore, I did not realise that "l" could be used as a prefix! 🤯

Incidentally, this input is available in the Windows IME, but not in the previous Mac IME (ことえり).
(Input with "x" as a prefix was supported in both, so I chose it.)

Currently, input using "l" as a prefix seems to be supported in both environments.
In other words, if possible, it would be helpful to both you and me if you could make it compatible with both "l" and "x".
