Now that you have added the time on top of the objects, I would like to make another suggestion.
It would be to add colors based on the time remaining for the object to be deleted.
-- Example:--
- Between +5 and 2 minutes could be set to light green "§a".
- Between 2 and 1 minutes it could be orange "§6".
- After 1 minute it could turn light red "§c".
This is something very "cosmetic" but it gives an original touch, I don't know if you think it's a good idea to add it, and if you think about adding it to not affect players who want to put a specific color for the time you could put it something like this:
# Show remaining time to disappear in item's nametag
display-time:
# Set this to false if your server is lagging
enabled: false
# Set this to false if you want to use your own colors
colors: true
# Text to be set in item's nametag
# {MINUTE}, {SECOND}, {TIME}
# Set this to "{MINUTE}:{SECOND} {TIME}" will be shown as "01:20 01 minute" (example)
text: "{MINUTE}:{SECOND}"
...
If you don't feel like doing it just close the idea, you don't have to give me reasons why you close it xd
