I’ll be watching this discussion, as I’m currently using Remmina. It meet the bare minimum of SSH & RDP, but it doesn’t have a clear method to organize connections and instead uses a big list. I also find the interface a tad counterintuitive, so maybe I’m just using it wrong.
It also seems to have a bug where it launches twice whenever I start my computer. So I have to close one.
My library also offers a membership with Flipster (magazines).
