@edk Hi!
There is already “news” to that:
On the one hand, the new “Fill” button will become larger ([PM-16102] Add min width on interactive badges by vleague2 · Pull Request #12514 · bitwarden/clients · GitHub) and additionally, the clickable area around that button will get larger ([PM-16102] Increase clickable area for bit-item actions by vleague2 · Pull Request #12450 · bitwarden/clients · GitHub).
On the other hand, the old auto-fill behaviour (clicking the item that get’s shown as an auto-fill suggestion leads to auto-fill) will get back as an option ([PM-16428] Option for primary click action to autofill on Vault view by kspearrin · Pull Request #12557 · bitwarden/clients · GitHub).
Update: The old auto-fill behaviour comes back as an option with extension version 2024.12.4. Can be activated by: Settings → Auto-fill → “Click items to autofill on Vault view”
