Would it be possible to have the option for both? I like the full screen for reading back, but I also like the half screen for inserting quotes and comparing my answer to the post I’m replying to. At the moment, when I minimise it places the cursor to the end of the composer text, and pops the quote there (when I wanted to put it mid post).
Could I have a button that toggles half screen/full screen (& minimise)?
