The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.
About Quick Subject Edit
Gmail can already change the subject of a reply. It's just buried: open the
caret next to the recipient, find "Edit subject" among the reply and forward
options, and click it.
Quick Subject Edit does that for you the moment a reply or forward opens, so
the subject line is ready to edit.
WHAT TO EXPECT
- Gmail turns the compose into a separate window when the subject becomes
editable. That is Gmail's own behaviour for this action, not something the
extension adds. Your quoted thread and forwarded message come across intact.
- It only acts on a compose you have not written in yet. If you have already
started typing, it leaves the message alone.
PRIVACY
- No permissions beyond running on mail.google.com.
- No network requests, no storage, no analytics, no tracking.
- Your email content is never read, copied, logged, or sent anywhere.
