@jbb23 Welcome to the forum!
Consider voting for the feature request “Customizable Window Size for Browser Extension”.
You can disable the display of credit cards on the Tab page (by unchecking “Show cards on Tab page” under Settings > Options), but you cannot change the order in which information is displayed (Logins, Cards, Identities).
You might also try using the right-click context menu (Right-click → Bitwarden > Auto-fill identity >), to see if that work flow is more convenient for you.
