This is my unofficial port of this mod by Mattiewagg and it is a great mod that now is fully functional in SSE. In the comments of the original post Mattiewagg gives full permission for anyone attempting to port the mod so here it is.

Description
Read the original mod description if you want the full experience. I'll briefly summarise the features here:

- Allows you to set items as "Keepsakes" using a configurable hotkey 
- "Keepsakes" will not be sold or dropped straight away, instead a prompt will come up on the screen asking if you really want to do this
- Optional Disarming option where if you are disarmed, for example by a draugr deathlord, it will ask you if you want to lose your weapon
- Full configuration available through an MCM menu to allow you to set your preferences and keybinds easily

If you have any questions, first check the original mod page and it's F.A.Q. for the answers and then ask here.



Installation
Simple, use a mod manager of your choice, I recommend MO2.

Manually: Just place the files in the zip folder into your Skyrim Data folder and activate the ESP in the launcher
