I’d like to remind you of our naming conventions before: https://packagecontrol.io/docs/submitting_a_package#Step_2
“SubTerminal” would pass, imo, but I couldn’t accept “SublimelyTerminal”. I thought of a few different names, like “Subliminal” or “Subterminal”, but I’m not sure they get the “terminal” aspect across. Will report back once I have an idea, though.
I can think of some plays on terminal itself, like “Terminality”. … actually, I like that.
