[Feature request] Clean list button

[Efesto]

Would be cool to have a button for cleaning the controller actions list, in a similar way as the clear button in Chrome Developer Tools in Network tab

You can do this now, but it's not very obvious. I only found it from a web search. In the README it mentions:

You can clear the panel with the usual shortcuts of ⌘+k or ctrl+l.
