@91volt, I have noticed the followings:

• Use Learn More instead of Learn more in the UI if IDE2 wants to follow to command label naming convention.
• Use Sign in to Arduino Cloud instead of Sign in with Arduino Cloud.
  What do you think?

@91volt, I also need instructions on where the Go to Profile leads. Thank you!

I know that the profile page URL is https://id.arduino.cc/. When I log in with SSO in the browser and navigate to this page, it loads my profile.

Problem: an IDE2 user might be logged in with a different account in IDE2 than the browser, so navigating to the https://id.arduino.cc location from IDE2 can be incorrect.

• My take is that the writing rules needs to be better defined, for now is ok leaving it as implemented
• Fine with me "Sign to Arduino Cloud"
• The Cloud Sketchbook doesn't provide features to handle multiple accounts for now, considering that is ok redirecting to the generic id.arduino.cc when the user click on "Go to profile".

Can you please explain what you mean? Thanks!

I haven't found any Arduino guidelines on label conventions, it is a topic that needs to be addressed with other teams.
Looking into other labelling conventions it looks like all the other internal words should begins with lowercase (reference).
So my take is to leave it as you implemented it, since there are no clear rules right now.
