Add hotkey "P" to the tooltip of Liquify's Preview checkbox, and everywhere else
There are text prompts with the hotkeys for the Tools.

Add the same for the preview checkbox (in Liquify and other filters)

Turning a preview on/off with a hotkey is more convenient than trying to click precisely into a smaaaall checkbox. I didn't guess to check the letter "P" and I had to ask it here on the forum. It's not mentioned in the text prompt, though it should be.
