On your first request, mine display in XXXX XXXX XXXX XXXX format, possibly because I put spaces between the blocks of four digits. They go into most websites fine, though not all.
This feature would be as useful as simple. While on mobile device, I had to enter credit card’s information on several online markets. Every field on the credit cards’ form has a copy button (on the right side of the field), allowing to rapidly switch between apps and paste the data, except for the field ‘Name’. If you want to copy that field, you need to enter edit mode (to be able to actually select and copy it).
This is a minor feature that would make the mobile experience a little better.
I request developers to work on point number 1 as well. It’s a relatively small change and it’ll greatly effect the readability of saved credit card numbers. Right now, It’s one of the more annoying things about bitwarden for me.
