Terminus doesn’t support automatically re-opening terminals that were open at the time when Sublime closed because in the general case, that’s not possible (for example, imagine you’re in a terminal in the middle of running some program when you quit Sublime ; how would Terminus know how to get that arbitrary program back into the same state it was before).
However, the README includes two key binding examples:
{
"keys": ["alt+`"], "command": "toggle_terminus_panel"
}
and:
{
"keys": ["ctrl+alt+t"], "command": "terminus_open", "args": {
"cwd": "${file_path:${folder}}"
}
}
The first one toggles a panel at the bottom of the window open and closed with a terminal in it; the first time you do it in any session the terminal will be created, making it transparent to you that it’s happening. The second one opens the terminal in a regular tab instead, if you want it always visible.
There’s also a third binding that uses the Origami package:
{
"keys": ["ctrl+alt+t"],
"command": "terminus_open",
"args": {
"post_window_hooks": [
["carry_file_to_pane", {"direction": "down"}]
]
}
}
Arguably the panel is the nicer option because it’s easy to hide, but the Origami option may also be useful to you if you want the terminal to be always visible. In that case you need to manually press the key to open the terminal though (and old terminal tabs will tend to hang around unless you close them).
