Hi Marc, thanks for the candid feedback.

I agree that there are sensible improvements we can make in the guides feature. We are confident though, that even with some of the use-cases you mentioned not being covered, it still adds value to designers workflows as is. We don't want to keep this functionality unreleased for an extra 2-3 months while still working on those kinks when designers can derive sensible value from the feature today!

With regards to copy pasting guides between artboards/documents and clear guides - that functionality does exist and is implemented (via the View>Guides Menu).

We are actively working on addressing some of your feedback soon, namely guide creation when zoomed in and showing the guide position (without moving it).

I'm curious what are your use-cases for guides being positioned at fractional values (10.5px) - what are the scenarios where those would be helpful for you?

And the last thought ... I actually believe that us not shying away to do things differently (guides without rulers, in this example) and then having this sort of constructive conversations will result in better tools for designers in the long term.
