I just want to talk to the folks who made the language switching logic so complicated instead of just a constant rotation like desktop IMEs. It seems like they expect the user to remember the previous language or prioritize languages in a clear order, but did it not occur to them that I might switch languages chaotically (A->C->D->B), keep it there, then hours later when I forgot what $previousLanguage was and press switch, I might as well be spinning a roulette?
