The Record Manager field is not editable in List Views.
This means that if you have a list of 100 new company records that you just imported, they will, by default have YOUR name as the Record Manager. If you need to edit these to change them to the names of the actual Account Managers who will be looking after those Companies you have to constantly flick between Company List View and Company Detail View in order to edit them.
We need the ability to edit Record Manager fields in list views.
It would also be useful if the Company views worked in the same way as Contact views so you could lookup the companies of interest from the Company List view then change to Company Detail view and scroll through just the Company records you selected using left/right arrows.
