Feature Request: Custom Retrieval Ratios

[MrVauxs]

As the title suggests, it would be great to have the ability to define what kinds of ammo or specific items have what recovery rates.
For example:
If you have a homebrew Metal Dart that you can retrieve 80% of after battle, it would be reflected by this module.
If you have a fragile or plenty of one-use items such as bombs, the module would recover 0% of them.
etc. etc.

As for suggestions on how to implement this, perhaps a configurable list of item names with their retrieval ratios or percentages.
"Dart": 50%
"Metal Dart": "80%"
etc. etc.

This feature most likely requires a bit of a rewrite of the module.

I would like to see this as well.

I could certainly envision how to implement this from the module side, same with the round up/down toggle in #2 . Main obstacle at the moment is that I haven't experimented at all with module settings yet, and am prepping a large city in my current campaign. If You know how to create the settings and submit that as a PR I will happily wire up the backend; otherwise, I should have time to take a stab at this within the next month, will do my best
