I'm sorry but we won't add such a feature as it goes against the human interface guidelines for macOS.
Try this with Terminal.app (or basically any app on the platform) and you will observe the same behavior.
Thanks Felix, I wasn't aware of this. I've never used a Mac so this is new to me.
Left clicking in a RoyalTSX remote connection brings focus to that connection. Right clicking does not, but does transfer the clipboard in terminal sessions. Is it possible to make right-clicking not only paste the clipboard, but also change window focus? As is, if I right click to paste from another application and hit enter, it will hit enter in my previously focused window.
