- Remove spurious whitespace in chat input box on page load being added because text area element was ending on newline - Do not insert newline in message when send message by hitting enter key This would be more evident when send message with cursor in the middle of the sentence, as a newline would be inserted at the cursor point - Remove chat message separator tokens from model output. Model sometimes starts to output text in it's chat format
