I don’t know what you mean by supports tray but have you tried KDE connect? It has a lot more features than just sending files but I use it for a few things.
And if you don’t care about having GUI, I love miniserve for sharing files. It’ll open a web server and you can connect to it to download/upload files.


Sorry I forgot to respond.
The thing that triggered it was when I shared an xkcd link. I have seen it a lot here but I guess it’s niche. And knowing about tardigrades, and many weird biology knowledge about bugs, bacteria, and such. We’re both super nerdy about science, but at the same time we hadn’t met anyone else be this nerdy about science in real life.
