Fix #238

Todo

• Add telemetry notice on first load and request for approval
• Persist uuid between sessions
• Persist telemetry preferences between sessions

Metrics

Things worth tracking (for usage and UX improvements)

• Page/tab visits
• Interaction with buttons / clickable / hoverable items
• Keyboard shortcut interactions
• Runtime errors + stack traces
• Event source (exchange name for compatibility - useful if runtime errors occur)

Things we definitely shouldn't be tracking

• GraphQL queries, variables, and responses
• Events coming from the devtools exchange
• Keypresses which are not associated with a known keyboard shortcut
• Anything outside of devtools (i.e. content script / the exchange)

Let me know what you need me to look at here, Andy. I am a little out of my technical depth.

No need for anything at the moment thanks @formidableamy, just wanted to keep you in the loop as to the progress of this!
