Like another one of this devs plugins, I LOVE LOVE LOVE the fake review below me.
How do I know its fake?
Because there is absolutely NOTHING in the code of this plugin regarding PlaceholderAPI.

Let's break down the reason for this 1 star:
1) Asking friends for fake reviews. This just makes you look bad.

2) Using AI to write plugins. AI doesn't do the greatest job. It also makes you look extremely lazy.
(incase the dev changes something, at the time of writing this review, contributors at the top said "Raytracers (and ai sob)"
So they're admitting to using AI.

3) Groups don't work.
""
# Group-specific prefixes and suffixes
# These will be applied based on permission groups
groups:
""
Um.... yeah no.

Here is the code to get the player's group:
""
private String getPermissionGroup(Player player) {
return player.isOp() ? "admin" : "default";
}
""
So basically the "moderator" and "vip" groups in the default config wont work, nor will any other groups you have in your perm plugin.
There is nothing in the code to get the player's group from a permission plugin (there is no hook into vault or anything)

4) The plugin has some built in placeholders (NOT PlaceholderAPI placeholders), but no where are they documented which ones can you use. They're limited, only 7 that I can see. But you'd have to decompile the jar to figure out hat they are.

5) According to the plugin.yml:
"author: Hypnothizes" <-- who is this? Is this your other name? Or did you steal code?

Summary:
This is just a janky, AI written plugin from a lazy author.
Also the fake review below me is hilarious.

Great tab plugin! Simple, and easy to use. I appreciate the PlaceholderAPI support.
