Maybe it would help if you could tell me, why you would need something like inventory notes. The possibilities i can see are fairly limited.
Main reason as stated above is to mark an item for sale so do not have to rely on memory and/or check wiki again before selling, other possible reasons are:
- keep for crafting (notes could then state for what charm(s) but can do this currently on paper/spreadsheet etc)
- keep for building (but can remember this easily enough generally)
- keep for donation to guild ie donate once red
- keep to feed to pet (wouldn't use it myself but could be a reason)
At its most basic:
- storage items - mark for future reclaimation, anything else is presumably saleable
- inventory items - mark for sale where reclaimed before got decent price or now no longer useful and can be sold to free up space
For this would need one toggle on both inventory and storage items which could perhaps go to the left of exchange rates on second row where there is seemingly a gap?
