questions about the stash tabs for a new player

I've been playing the game enough to believe i'll continue playing for a while, so i upgraded to the lord of ogham supporter pack and with all the points so far bought only the following stash tabs:

4x premium upgrades (for the 4 tabs you get for free)
6x premium stash tab bundle (so i have enough space to organize for all my characters, and to store stuff like maps, tablets, trial keys etc.
1x Premium Quad stash. Simply because this was recommended as a dump tab to sort out later.

then ive bought the Currency, Gems, Essence, Delerium and unique collection tabs to furter sort out the inventory.


There are a few things im wondering about:

Folders: ive made a few folders to futher organize, but is there any option to colour the folder, or show the contents in the dropdown tab list?

Unique Tab: there are question marks for items you havent found, but ive put in a unique, and then taken it out on another caracter, but the card changed back to question marks. Shouldnt the name / item remain (but greyed out) so you know you've found it before, but it isnt currently in your stash? Seems weird to me that it goes back to "unknown".

Additional Slots in the Delirium tab.
On the delirum tab there's 21 empty slots, which i thought could be used to store Catalysts. Or that they would work the same as the 14 empty slots in currency tab, or the 4 empty slots in the essences tab. However no matter what item i try, i cant fit anything in those empty slots. What are those slots used for ? and if you cant use them, why are they there?

Bump. Wondering about some of those things too.

I searched for "stash tabs" to try and find which stash tabs do what but they mostly seem to be advice about what the most important tabs to get on a limited budget are. I'll gladly shell out some money for more tabs than what I can afford from the early access purchase but I don't know which ones do anything at all in PoE 2. For example, I have tons of runes, waystones and djinn barya stones I want to put in an affinity tab so I don't have to manually swap to the tab I put them in every time I empty my inventory.

- Can "maps" stash tabs hold waystones?
- Do "fragment" stash tabs do anything in PoE 2?
- Does the "Ultimatum" stash tab hold Djinn Baryas and those other ones for Temple of Chaos?
- Does the "delirium" stash tab do anything in PoE 2? Like hold distilled potions or anything?
