Concentration
I don't know my version or loader
Introduction
Added borderless support for Minecraft 1.20.6+.
Version 1.0.0 requires Embeddium. Not supports Sodium on Fabric platform.
Version 1.0.1 requires Sodium as dependency.
Version 1.0.2+ doesn't require any mods as dependencies!
For Modpackers
You can use my mod in your modpack, however please don't provide the mod file directly, use mrpack instead.
Screenshots
(This page has been removed after 1.0.1, and borderless fullscreen replaced native fullscreen directly)
(This is the new config screen, NeoForge available without any dependency, Fabric requires ModMenu to open this page)
Compatiblility
Sodium
Totally fine, no conflicts.
Embeddium
Totally fine, no conflicts.
Vulkan Mod
As a user reported in issue#7, the borderless fullscreen provided by Vulkan Mod not works. So I add compatibility with Vulkan Mod so that you can use Concentration as an alternative borderless fullscreen with Vulkan Mod.
Known Issues
The option text won't change when you press fullscreen shortcut in the options page. This actually is sodium and embeddium problem not Concentration problem.
