ShowContainerContents

This is a simple quality of life mod that lets you see the contents of a container, as well as its remaining capacity in the interact hover text.
You can configure the following:
Maximum entries to show - default '-1', meaning unlimited
Sort type - Name, Value, or Weight - default 'Value'
Sort ascending - default 'false'
Entry text - default '<color=#AAAAAAFF>{0} {1}</color>' ({0} is replaced by the amount and {1} is replaced by the item name)
Overflow text - if more items than max entries - default '<color=#AAAAAAFF>...</color>'
Capacity text - default '<color=#FFFFAAFF> {0}/{1}</color>' ({0} is replaced by the slots used and {1} is replaced by total slots)
Colors are RRGGBBAA hexadecimal (Alpha doesn't seem to do anything). For example, to get the colors in the first screenshot:
'EntryText = <color=#FFFFAAFF>{0}</color> <color=#AAFFAAFF>{1}</color>'
Apparently if you use BetterUI, you need to set the following in the BetterUI config file:
'chestHasRoomStyle = 0'

Config

A config file 'BepInEx/config/aedenthorn.ShowContainerContents.cfg' is created after running the game once with this mod.
You can adjust the config values by editing this file using a text editor or in-game using the Config Manager: https://www.nexusmods.com/valheim/mods/740
To reload the config from the config file, type showcontainercontents reset into the game's console (F5).

To install manually, place the .dll file in the BepInEx/plugins folder. You will need BepInEx.
