This is a major update. Old configuration files are not compatible. A migration guide is available here: https://github.com/ServerSelectorX/ServerSelectorX/wiki/Migration-guide-v2-to-v3

New features:

• 'conditional' section replacing the previous online, offline, and dynamic sections. This allows for new functionality, you can now also change the item based on PlaceholderAPI placeholders, potion effects, open menus, and more!
• 1.19 support
• 'chat' action to send chat message from the player clicking an item
• Allow configuring actions for empty slots (for example for servers using a resource pack to retexture the menu)

Bug fixes:

• Fixed error spam when opening menu with invalid config
• Fixed '/ssx openmenu' command
• Fixed IndexOutOfBoundsException when using blank materials
• Fixed 'nbt' option. it now works instead of sending a confusing "compound" warning
