[ok] New UI - Change A/C registration

[Mr.HP]

Could you please add: "Next available number"; of course this option is available only if default registration format is set already. The purpose is to quickly set number for return leased A/C; or for swapping A/C

Otherwise, please make it similar to the previous version

Previously, when changing registration, the popup appears with the current registration number selected already (i.e. we can type in the new number right away and press enter; no mouse clicking required). If the new number is not valid, the pop up was still there and we can key in another number

The new UI requires mouse clicking to highlight the current number, only then we can key in new number. If we put in occupied number, the pop up is closed immediately, and have to restart the whole procedure

Thanks
