Hey @ghuntley! Here's some early feedback on this change.

suggestion: Overall, I think it would be better to keep this form a) anonymous and b) optional. Opening a new tab after installing or removing the extension is already a bit intrusive but I'm also in favor of keeping this flow. However, including form elements for user input like name and email could easily discourage users from considering filling out any inputs on the form.

If we still want to collect other user data like name and email, I'd vote for making it more clear that this data a) is optional and b) only used in case a user is interested in hearing back from us for this specific submission. Even better, we could only show this form when a specific checkbox option is selected as it doesn't make sense for some options like I prefer my local development.

In terms of UX, I think we can improve a) the messaging, b) the tone of voice, and c) the checkbox options. Also, the text input elements introduced here could use better spacing (padding).

thought: A better alternative could be to proactively introduce help links where possible under each checkbox option or below the form. For example, linking directly to the screencasts, relevant documentation, etc. Many users still don't fully understand what dev environments are and this is a good opportunity for us to provide educational content or even suggest scheduling a call for help as included in the Free Trial email we're sending out.

Last but not least, we could use this PR only to fix #1009 and discuss this in a follow-up issue. 🏀
