[FEATURE] Add save success or failure message to both bottom and top of metadata form

[Danny-dK]

Is your feature request related to a problem? Please describe.

When filling in the long metadata form and clicking on save button at bottom of page, the success or failure of save is only visible at the top of the metadata form (so you have to scroll all the way up).

Describe the solution you'd like

Make save success message linked to locations of save button. That means both at the top and bottom of the page. There is no need for a floating save button in my opinion (and hence no need for a floating save success message).

Describe alternatives you've considered

Some sort of success icon next to the save button, but that icon should be a clear icon and be removed once the metadata file is being altered (so that the user knows when the user altered the form without those alteration being saved).
