SSH's Server Tabs.
For version 1.21.11, requires Fabric API.
This mod adds customizible tabs to the multiplayer server list so you can organize your servers better. It has icons, customizibility (right click a server tab), and easy to use (to create a server tab simply click the plus button and set the name, and optionally use the option bellow to change the icon.)
After creating this I double checked to see if other mods do the same thing, normally if I find a mod that does the same I will not post my mod, but in this case my mod has large enough design changes that I feel ok posting it. That's why it's called SSH's Server Tabs and not something like server tabs or server lists as it is my approach to an idea.
