Dear Aternos staff!
I'm sorry for the length of this post, but I tried to be as precise as possible. Here's 9 mods that I couldn't find with Aternos's search function that I'd love to see on my server. I linked the curseforge pages below with a short write-up for each mod. Thank you for your amazing work!
So here we go:
1) Iberia (https://minecraft.curseforge.com/projects/iberia)
It is a simple but clever mod for making the vanilla experience a little harder by preventing strip mining, hiding the coordinates and changing your spawn point every time you die. It's a really well made mod that is highly compatible with most other mods. Around 12k downloads so I wouldn't call it too obscure even though it isn't super well known.
2) V0id's smart backpacks (https://minecraft.curseforge.c…cts/v0ids-smart-backpacks)
Modular upgradeable backpack mod. Really lovely mod for transportable storage. 53k downloads.
3) Tumbleweed (https://minecraft.curseforge.com/projects/tumbleweed)
Almost 2 million downloads. Collect cute atmospheric tumbleweeds for items.
4) The Summoner (https://minecraft.curseforge.com/projects/the-summoner)
Even though it is still in beta, after thorough testing I have had zero issues with the mod. It adds a single powerful illager mob with unique fight mechanics and a powerful end game item. I see no reason not to add this as an option to download.
5) Stalker Creepers (https://minecraft.curseforge.com/projects/stalker-creepers)
Fun improvement to Creeper AI, so that they wait for you to turn around before they explode on you. 110k downloads.
6) Snow! Real Magic! (https://minecraft.curseforge.com/projects/snow-real-magic)
Improves snow behaviour (gravity, accumulation, behaviour with transparent blocks etc.) ~14k downloads
7)Snow accumulation (https://minecraft.curseforge.com/projects/snow-accumulation)
Highly compatible mod for better snow accumulation. 30k downloads
JJ Skill (https://minecraft.curseforge.com/projects/jj-skill)
Amazing rpg-style skill-mod. 19k downloads.
9) FlashFyre's Enchantments (https://minecraft.curseforge.com/projects/ffenchants)
My favourite mod for new enchantments in the game. Definitely deserves it's place here, even though it's a bit of a hidden gem.
