@zeitgenosse To me this looks like there is a time after the date, which is why it is cut off with "..." despite the fact that the plain date would fit.

Not sure what better way would be there to display and entire date and time with this little space.

If breaking the text into multiple lines is not an option due to vertical space constraints, pretty much all you can do is show the entire date and time on hovering over it. Which is non-obvious and needs to be actively explored by the user.

@roskakori Another issue is that the application doesn't respect my system locale (en-DK with ISO 8601 date). Otherwise it yould have at least displayed 2025-04-3…, which would have been more useful to me, as in this case the year is more important than the month and day.

However, the fact that the column didn't automatically expand in the first place (despite there being more than enough horizontal space) turned out to be to some weird Qt5 glitch that I am no longer able to reproduce.
