Collapsible "Add new watch" form in watchlist

[Batwam]

Hello,

I would like to kindly suggest making the "Add new watch" form on the home page collapsible in order to maximise the space for the watchlist itself. In my opinion, the main purpose of the main "watchlist" page is to quickly see the list of website being monitored and this top section takes too much space, especially when accessing on mobile where the content of the watchlist cannot be seen without scrolling down.

Basic implementation shown below using a <details> html block for instance.
