It'd be great if I could add a single 1x1 shortcut to my home screen that would connect to a selected host.

Another thought, it'd be even better if I could create a shortcut that would let me select a host and a particular snippet to execute on that host. I am aware that a snippet can be selected to run when a particular host is opened, but it would be messy to make new hosts just to be able to run different snippets via different shortcuts.
