Context
Currently, when I open the detailed view of a row of a table, a side panel is displayed to show comments, whether there is comments or not. While this panel is useful to make comments, it can be troublesome for people who do not want to comment or see comments.
Solution
Having a collapse button like the one used to display the main panel on the left (the one displaying databases, tables, subscriptions etc.). When a user check the detailed view, he can see comments, and can choose to hide this side panel. When collapsed, it shows a << button with a number on it which could be the numbers of comments made on the card.
Having such options could also improve the UX for mobile user : by default, it could hide comments (since screen size is very limited), but can be still displayable if wanted by the user
