Add a timer option for dropped backpackSolved
If I set option
  "Drop on Death (true/false)": true,​

and will not grant permission

backpacks.keepondeath

to user, backpack will be dropped near players dead body. This is normal, but it lays there for a very short time.
Please, add an option (in minutes) to keep it lying there and waiting for player come and loot it.

 
How long would you want the backpack to remain?

Some plugins that clean up entities will delete containers like this earlier than normal which could conflict. Might you be running any of those?
Well, for me 30 minutes is great option. I used another (private) version without any issues.

When I tested first time, time was like 5 minutes, or so and 2 times I checked it was disappearing fast. Some additional testing now showed 50+ minutes. I'm confused a bit. Sorry for bothering you, maybe it's not about the plugin. I just didn't had those "5 minutes" timings with previous plugin, so I thought it will be only 5 minutes everytime...
I'll try to test more and understand what caused that short time I had in first tests.

I use "where's my corpse" plugin which works great even though its no longer maintained, i have that set for 20 minutes and even though the corpse disappears the loot is still there, been working ok for many years with no problems
