This is how the search window looks after first start, the column names are cut of when there are longish names:
And after a search (I added the origin column manually here, because I'm on an older test version without T7155):
You see that the width is still the same.
I'm not sure what is the best approach, one might do something similar to T7227 or T7082.
Edit 2024-08-19 strike through of obsolete suggestions:
And for columns 3 (User-ID/Status) and 5 (Valid until) the tooltip says that those values can not be validated at this point. Therefore I propose to remove those columns from the default columns of the search window.
If both items are not addressed together, please split the ticket.
