What I'd like added is pretty self explanatory, any visual upgrading mod is fair game.
Also I'll check that out! If It's worthwhile I'll add it and mention you in the patch notes.
(Also this is accepted).

I think these could add a lot more variety to shops and pair well with the already included eyeguy's EXTRA NPCs.

Hope you don't mind that I suggested more than one mod

Suggesting more than one mod is fine :)
However, in saying that, I don't think I'd add any of those mostly due to the fact that they stray very far from vanilla Tboi, there's never dialogue of any kind anywhere else in the game and the shopkeeper variety is quite silly. Not to say they aren't good mods, just that I don't consider them very accurate to the actual game.

I saw this a week ago and contemplated adding it, however, many modded enemies use the same cursed eye costume design to make them "teleporty" and TR resprites the item anyway.

Small additions to make certaint items reflect the character that is currently using them

https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2836316830

There is also this pack which adds even more unique items, though this one might be a bit of a stretch

https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2541289729

this adds a skin for every sin depending on the current floor (though it invalidates any sins resprite)

https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1292629863

This one makes Mega Satan have a unique Boss theme, instead of sharing it with regular Satan

Hope I'm not exaggerating too much with all of my requests.

Don't worry, the more requests the better.
I always disliked a lot of the unique Isaac mods. The only one I thought might fit was the unique birthrights one. The rest all feel redundant and or unnecessary. I mean, It's always Isaac's soul that is in all the characters because it's always him, so the unique ghosts don't make much sense. Unique Mega Isaac's is almost good until you realise that your character changes it's appearance throughout the run, when they become big, the original character state is a bit disorienting, by default it's just Isaac but the skin colour changes depending on items and I think that's better. The mini-Isaac one and the unique C-section one are both a bit weird, why would stem cell babies and unborn fetuses adopt the characters clothes and stuff?
And despite all those being solid reasons as to why i wouldn't add them, the main reason is that most modded character's won't have compatibility with them all, creating a rather janky and unbalanced visual experience.
I actually plan on adding unique sins once they fully complete the mod, up to the quality that they want it to be.
And the unique Mega Satan music is way unnecessary because it already has it's own music and I think replacing it would be trading one good song for another for no reason.

Wait really?
Then I'll check that out.

Accepted!

Quality of life mod for boss rush allowing you to see the number of the current wave
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2635267643
Makes Every boss have it's own custom boss bar
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2489006943
Shows the hidden stat "Planetarium chance", was also going to suggest the Damage Multiplier mod but it's apparently broken
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2824831207
This makes it so that getting a second copy of certaint powerful items correctly applies their effect instead of doing nothing
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2826759722
This changes the Behaviour of Wizoobs so that they may appear faster after vanishing (this is a change to the enemy's behaviour, but I did see better pooters in the included mods so maybe this might make the cut)

I don't have much hopes that this one will be accepted, but it doesn't hurt to try
Also I was fairly disappointed when the completion award for a character whose hole premise was to "Control their destiny" was random in nature

I think, out of these, the only ones worth adding are the planetarium chance and boss rush wave counter. Also the boss bars mod reminded me of another mod called "Fancy boss hp bars" or something, that's honestly the main reason I don't want to add the custom boss ones. The fancy mod makes it have a spawn and death animation and it's super cool.. Just very buggy at the moment so I'm waiting for it to get fixed.

I think I like it a little more than the current Apollyon resprite, plus it comes with the tainted version.

https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2851847497
I just never understood why the prides look the way they do, so I like this one.

I would like to have an Apollyon resprite eventually but that one is done pretty poorly, it looks like metal rather than skin or rock, which are the materials I always thought Apollyon would be made of.
And I already use a pride resprite from a different mod that I prefer much more.

The slug is definitely too memey but it's pretty cute.
The others I'll check out later today.
