Add conversation bubble as default for adding a new conversation when clicking + sign of an item/sub with expend button ((UX/UI))

Hi, The experience today is when I click on + to add a conversation or edit it, there’s a pop up window of conversation to the right of the screen.
It is very not user friendly expecially for efficient work.
Sometimes I just want to add a sentence.
I suggest like google experience, when I click on the + there’s a small window to the right of the + (like a bubble) where I update my current sentence and to the top of that buble an expend button which allows to expend it to the conversation full window.
