I use Ubuntu 20.04, and connect to many servers by SSH terminal. Previously I used a desktop launcher from the left hand launcher. This launcher was in my .local/share/applications folder. I could right click on the launcher and it would show me a list of my servers that I could connect to. There must be many people like me having to log into multiple servers. What's the current "best" way? Maybe some extension like the "places" dropdown on Ubuntu 20.04 / Gnome extensions.
That launcher of mine looked like:
