Save actual stats of items

[ChaosMarc]

First of all: What a great tool :) Thank you for creating it!

I'm missing one thing though. If I want to know if an item I have just found is perfect I have to read all the properties listed in the details popup to see where the stats of my item are in the ranges. I would like to propose to split the stats an item has into static and variable stats (dmg ranges are static). In addition I'd like to have input fields (maybe different kinds depending on the type of the stat, e.g. slider for plan number ranges, dropdown for random skills/trees, ...) to save the actual stats of an item and the character it's on. To round this up I would love an option to save multiple items (with their actual stats) in the grail tracker. This way the scope of this tool would increase from just a grail tracker to a full blown item management system :)

With this #55 could be implemented in one go 😇

To split my rambling above into "small" tasks:

• split stats in ItemList.tsx.ts into variable and static subgroups
• add possibility to "store" items with the info on which char they're on
• offer input fields for variable stats in the details popup
  • ethereal status and #sockets could be listed for applicable item too
