Impossible to figure out which tab to purchase for what I need in POE2

PLEASE LOWER THE DIFFICULTY OF ACT 3 and 4 BOSSES!
I am so tired of dying to Act bosses I just may ragequit permanently to this game and never stream it again. Anywho...
I play 3 kinds of avatars in POE2. I want my tabs to reflect the loot they covet and farm. I have no idea how to purchase/upgrade the existing tabs I have to what I need done for all 3 avatars. Yes, I have seen the stash tabs in the 'Shop' but this does not mean its easy to figure out what is needed to buy there.

My goal is to have all 3 avatars have a Quad tab to farm their equipment. The ability to INCREASE THE VISUAL SURFACE OF SAID QUAD TABS WOULD BE NICE! Some of us wear glasses and need to squint to see the tabs. Sorry you all have perfect vision but why are the Quad tabs so small?

From top to bottom what tabs look like in STASH (and what I want done to them will be in RED letters):
1.) Quad tab named 'Warrior' (purchased this to farm equipment, works fine)
2.) Regular tab named 'Witch 1' (need to upgrade this specific tab into a Quad tab. Not sure how this is done. There is no 'Upgrade regular tab to Quad tab option I can see anywhere.)
3.) Regular tab named 'Witch 2' (need to upgrade this to a Quad tab and rename it 'Druid'. Not sure how to do this. Same as #2 no option to upgrade a regular tab to a Quad tab anywhere. If no option then NO TRANSACTION.)
4.) 'Rings' tab (upgraded premium tab, works fine)
5.) 'Rune & Charm' tab (upgraded premium tab, need to purchase Essence tab which is cluttering this tab so Essences can be offloaded out of this tab. This is easy to do.)
6.) 'Gems' tab (purchased this, working as intended)
7.) 'Orbs' tab (purchased this, working as intended)

Plan to buy (but I have no desire right now since GGG hates its players to ever get into End-game farming. This is very true! I have been stuck for over 6 months (across 3 different toons now in Act 1-4 farming and can not get out of Act 4 because GGG does not have any idea how hard the end-Act bosses are. They are incapable of knowing the pain and shoot themselves in the foot when it comes to earning revenue for Stash tabs:
A.) Merchant Stash tab, not sure if a regular tab can be converted or must be purchased separately. No where is this shown or talked about. If I can't figure it out THEN I AM NOT BUYING IT, PERIOD! Your loss, GGG!
B.) Map Stash tab (I will NEVER Get this tab because ACT 4 is so hard to get out of because the bosses are SO HARD TO DEFEAT YOU WILL NEVER GET MY MONEY SINCE YOU HATE YOUR PLAYERS EVER DEFEATING THE BOSSES. No Maps tab required since GGG hates players ever getting into end-game progression. Sucks to be you, GGG! Now why would anyone purchase something they have not seen or can use like the 'Map Stash tabs? Does GGG want to earn money or do they not? I am confused.
C.) Augment Stash tab, plan to buy once I ever get out of Act 4. Not possible in this lifetime and this fact makes me ragequit on Stream constantly. LOWER THE DIFFICULTY OF THE ACT 3 AND 4 BOSSES, JEBUS! Are the devs insane people or hate their potentially paying customers?

If you are not trolling and truly struggeling with the campaign, make sure you are not underleveled, farm a bit of upgrades, or find a leveling guide for your character, there are plenty out there.

The game is not really that hard.

I see a lot of talk about 0.1% top players, but i never saw anyone talking about 0.1% bottom players, because it seems like OP is one of them.

I assume you do your own build, which is big W, but reading how much you struggle, i would suggest following some build guide, because no way you will struggle in campaign this much as long as you do any normal build.

And don't get me wrong, but you sound legit like bottom 0.1% of players, struggling in situations where almost every player has 0 issues.

As for stashtabs, currency + map(waystone) tabs, then whatever you need.

You can convert premium stash tabs to merchant stash for free if those premium stash tabs were purchased before august 2025. https://www.pathofexile.com/my-account/merchants-tabs
Otherwise just buy it, might not need more than 1 for a while considering youre new.

Before you buy any more tabs, OP, tell us a bit more about the builds you're playing (class, ascendancy, current character level and primary skills or just post PoBs). I'm sure we can help you optimize one of your characters so that you'll be able to beat act 4.

In general, as long as you upgrade your weapons somewhat regularly, level up your skill gems (and use jewellers orbs on your primary skills to add additional support gems) as soon as possible and get close to capping your resistances (anything above ~50% fire, cold + lightning res should be good enough for act 4), you should be able to rather easily beat all bosses in act 4. Regarding your skill tree, make sure to path towards the damage (and ailment) types your skills are actually using and look for defensive stats close by that match your character's primary defense (armour, evasion, es).
