Sublime Text 3 - integrated terminal?

Terminus does this. Supports both Unix and Windows. Works great.

In View (on Windows)

In Panel (on Unix)

I installed the Sublime package TerminalView that can show a terminal window within Sublime in a separate tab.

It works with MacOS or Linux but is no longer actively supported.

Installation:

1. Open the command palette (Cmd+Shift+P on Mac, Ctrl+Shift+P on Windows) and find Package Control: Install Package
2. Search for TerminalView and hit Return to install.

The terminal windows has a few flaws (at least on macOS) as it seems to conflict with Sublime's keyboard shortcuts. I however use it only to automatically run unit tests when the edited program code changes. Therefore it works just fine. In that case it works best if I show the terminal window below the text editor. You can do so in the menu View > Layout > Rows: 2.

I tried Sublime package - TerminalView, quickly realized I couldn't copy paste things. Tried on MacOS.

Terminus(https://github.com/randy3k/Terminus ) looks good to me, it has two options

(i) opens in a tab(view)

(ii) opens also in a panel. (which I prefer most)
