Webflow adding responsive templates and vertical rulers

Hi!

So lately I’ve been designing a lot more mobile friendly sites and I own an iPhone SE which is a fairly small phone.
I’ve had to use Chrome’s “inspect” element and use the various phone templates and responsive resizing edge guides in order to see my websites on various devices I do not own.

I was wondering if this feature would be coming to Webflow anytime soon?
I sometimes think my website is mobile friendly but I come to realize it isn’t and I have to do some adjustments and margin tricks.

I don’t want to have to publish my website every time I make adjustments.

Any thoughts?
Thanks
