I guess the recent update created a gray bar on the left side of the canvas for responsive actions. I'm not sure what the technical term for it would be (Responsive Slider?). But I noticed it this morning when I got on Webflow.
Is it possible to make it not show unless you need it or want to use it? I made a little cheesy gif that kinda shows what I mean. I don't know if how y'all have it now is temporary, nor do I know what other plans you have for the UI. Just a suggestion/idea so it's not making the workspace smaller unless the users are working with it. If at all possible.
