Question:
[I was experimenting with breakpoints in the Wix Studio Editor. Now I need to reset the breakpoints and return to the initial status.]
Product:
[Wix Studio Editor]
What are you trying to achieve:
[Reset breakpoints and add a new breakpoint with 1920px.]
What have you already tried:
[Add a new breakpoint. Delete breakpoints. But I would like to start again with the initial values ]
Thank you for your help.
I did the reset manually adding these values: mobile 320- 750px, table 751-1000px, computer 1001px and up.
Suggestion: create a breakpoint reset button. Thank you.
Glad to hear you managed to resolve this!

@Rodrigo_Cerqueira Sounds like you were able to manually adjust the breakpoints! 
Keep in mind, the breakpoints are just ranges and most devices will fall within the entire range, so as long the site looks good in each range, you should be good to go.
I did note your request for the team! However, if you want your idea to become an official feature request, head on over to the Product Roadmap and click the ‘Request a Feature’ button.
