2 things:

- Jump Desktop works _a lot better_ than anything else in my experience (I live inside an iPad hooked up to XRDP) - Android terminal bindings are perfectly OK in https://play.google.com/store/apps/details?id=jackpal.androi..., so I'm curious as to what exactly was the problem you had (I also have an ODROID-U2 which I use as both an RDP client and an SSH/tmux client with extra smarts)
