item filter and item tiers info req

Having a bit of an issue with item filters, using neversinks, is there a version for showing all currency and tiered loot? Strict versions have strange hide rules.



As for item tiers...what does it mean? I was trying to find an in game answer and came up empty. In poe1 i can hover over an item and understand how powerful each stat and roll is, in poe2 i have no clue what "tier2" etc means. Further to this whats the difference between a tier drop and a non-tier of the same ilvl and base? I think i know the answer but there seems to be no way to tell if something is objectively better in game easily :s

it is same with poe1

+ we have extra tiers on "unidentifed items". basically: high tier items can't roll low tier affixes. higher is better but it is just for identify.
