A few notes:

• Attached spells don't appear to be working. I searched Command and got 0 results (staff of charming should have been there) and the same with Bless (Potion of Heroism not showing).
• The multiple entries don't add much beyond the single entry. If there is every variation of Adamantine Armor listed separately, I would want to know the type of armor (light, medium, heavy) and how my AC is calculated. The notes give some details (strength requirements and stealth disadvantage) but not everything. For weapons, I'd want to know damage and range.
• I'd also like to see the +'s in the notes since that is a searchable field.
• Notes are being cutoff even on desktop. There is no way to see the notes in the expanded view or item page.
• Source field isn't working, but that is likely due to using the SRD right now and not the DMG. I hope that these are condenced into one entry per item when additional sources are added.
• Consumable should be it's own field, like has charges, instead of a tag.
• There are some inconsistencies with items that have multiple versions. Adamantine chain shirt doesn't list immunity to crits in the notes, so it doesn't appear when I filter for the immunity effect type.
