In Server Share you can now host your own Minecraft server (Java Edition). It sets the server up, tries to open your router port automatically, and walks you through it if your router will not cooperate. When you are done, any other member of the group can host next and pick up the same world with all progress intact.
In the Minecraft tab you will also find a section for modded Minecraft. Server Share works out which mods the group uses and helps everyone install both those mods and the right mod loader, so playing modded with friends does not mean talking someone through a manual install.
Mod support currently covers mods hosted on Modrinth. Mods from CurseForge or installed by hand are listed for you but have to be installed yourself. This part is a work in progress and will keep improving.
On the UI side I have rebuilt the settings menu and cleaned up a lot of small things across the app to make it clearer and better looking.
