When Bulk Action is selected and a user has selected more than one- it would be advantageous for the individual action buttons on a record to disappear and the only button available to users is the bulk action- do for all button.
It’s confusing for users to have all the button choices shown at once. When the bulk action is enabled and they start selecting multiple items- sometimes they click an individual button thinking it will do it for all items- but it only works for the 1 item. So it’s not clear to them, when they want to do a bulk action, where to click and how to make that action work.
This is an awesome feature that at least for my clients I don’t use as often because it is functionally confusing for for them and their users.
