Stash tabs

[ColdRus]

Hello, everyone.
I'm new to PoE games.
The very 1st question before I start playing is what are those different types of STs?
Well, I do realise in general why I need them. For example, in Diablo 3 I just have several STs to put whatever I want to store in them and that's all. But in PoE games it looks like something different...
Gem, Flask, Currency and other STs... I got a little confused... Can some expirienced players explain this "system" to me?
PS: normal ST vs. premium one - what is the difference?

1.) you want a currency tab. it stores in all your orbs that upgrade items. transmutes, augments, regals, chaos, alchs, exalts, etc

2.) you want a premium tab. this basically makes you able to trade more efficiently because when you put the tab to be able to be seen to the public it gets automatically added to PoEs in house trading site that people use to look up items they might want to buy. If you dont buy this you're best bet at trading items is going to the trade chat in game.

3.) essence/delirium tabs. stores currency related to those mechanics. Essences, Distilled currency, etc.

4.) more stash tabs/ or more premium stash tabs. just choose whichever one

5.) fluff tabs such as Unique stash tab which stores every unique in the game but is limited to 1 copy.

gem stash tab. just stores skill gems/ uncut gems 500 limit

flask stash tab. stores flasks 500 limit

I think thats all of them as of right now

Currency and Gem is a must, and other stuff is optional

And a card tab if there even is such a thing as cards in PoE2.

Premium Quad also feels good because more stuff fits in it
