MacOS text substitutions work by automatically typing a predefined phrase when the user types a certain keyword. For example, typing "omw" could be automatically changed to "On my way". And so on, for common greetings and phrases.
The Kagi Translate input text field however does not seem to activate these substitutions. Instead leaving the key phrase as it has been typed.
Maybe some HTML class needs to be changed for the text field in Kagi Translate for MacOS to understand that the user types text here and substitutions should function?
