Simple LAN-based chat client

[lunar oasis]

I started working on this as a learning project, then added some features a friend requested to use it for a LAN party.
Features: toast notifications when window is inactive, auto-discover servers, host and client modes, clients are notified and DCed when host closes the server

Release: https://github.com/Tors-0/Networking/releases/tag/v1.0.0
Source Code: https://github.com/Tors-0/Networking/tree/master

I would love to get feedback on UI improvements, especially for the main menu

First of all, I would create a README file explaining what the project does

And do you really want IDE specific stuff in your project?

Then, I would recommend you to use a root package

i.e. put everything in a package like io.github.tors_0

and use subpackages for client, server, etc

Also, why does the server access client methods?

parameters should be camelCase

because the server class only runs if you are hosting a server and running a client, so there is no scenario where a server can be active and a client not active

fair idea, i just have the IDE stuff because otherwise i have to manually sync my IDE settings across devices, which is annoying
