As far as I can see, not one central location. It’s mainly in these three threads:
- Bitwarden Browser Extension UI Design Refresh - Early Preview Now Available
- Upcoming improvements to the extension preview based on your feedback
- Extension Preview Updated (this thread)
A relatively quick “workaround” could be, to go to your profile here in this forum and to “activity”. Depending on how many other posts you submitted, you could find your posts in the relevant threads relatively quickly.
