I'm unsure how many here use Tailscale, but here's an app that I've been working on. Feel free to critique it and tear it a new one. It's got a windowed UI and an applet, and `taildrop` is fully supported on it.
It is very opinionated, as I do use Caddy for reverse proxy and Beszel for monitoring, so those are built in.

You can also easily mount your remote machines- based on the user home directory- as remote drives in Cosmic Files… a little nice if you want a cheap cloud drive you own. And, for you machines that have `ssh` enabled, you can jump right into them from the app, it opens the ssh session for you in Cosmic Terminal.
