The default item displayed for each tag is a minecraft:name_tag, but the item ID can be customized in the YAML file.
After equipping tags, the selected slot will automatically change its display type to redstone. When not equipping tags, the type will revert to the previously set type in the tags.yml file.
New features for items in the GUI:
- Paper: Allows switching between pages.
- Beacon: Toggles between two states of the tags.
- The first state displays owned tags.
- The second state displays existing tags, excluding certain specific tags that are set to be hidden in the YAML file.

Updated file names:
- Config.yml (no changes required)
- Renamed custom.yml to tags.yml

Specific changes in the tags.yml file:
Default template:
- Permission: "Hologramstags.default"
- type: minecraft:name_tag (default type for each tag)
- Describe: (added description lines displayed in the GUI)
- "This is the coolest tag"
- Tags: /Hologramstags tags set [HologramsName] [HologramsDisplay] <line>
- "Line 1"
- "Line 2"
- Buffs: /Hologramstags add [HologramsName] <effect> <level>
- "HEALTH_BOOST:1"
- "EXP:1"
- The sorting of tags is based on the order in which players receive them: 0->1->2->?
- For admins, the sorting is based on the ranking in the tags.yml file.

Updated config.yml file:
- Default height of tags: 2.3
- Change time for switching tags to a different form (measured in ticks, 20 ticks = 1 second)
