I'd love to have a separate Liquify tool that sits in the standard toolbar that allows for the basic options of Liquify to be used on the canvas without opening a new window.
Using the Liquify feature in Procreate is very convenient, and it's nice to not need to set any view settings. You simply stay on the canvas and immediately see results.
I think this would be a great addition to have while still keeping the current Liquify filter for other use cases.
