Output pane

I like how Zachary solved showing keybindings using Alt+G shortcut. Not because I need these shortcuts, but it reminds me the output window in Sublime Text. What if micro would have such output pane? Where command outputs by example build results instead of switching to terminal?

I have something like "runner" plugin, this is part of it:

function mode1()
    local buf = CurView().Buf -- The current buffer
    if buf:FileType() == "go" then
        HandleShellCommand("go run " .. buf.Path, true, true)
    elseif buf:FileType() == "php" then
        HandleShellCommand("php " .. buf.Path, true, true)
    elseif buf:FileType() == "tcl" then
        HandleShellCommand("jimsh " .. buf.Path, true, true)
    elseif buf:FileType() == "lisp" then
        HandleShellCommand("newlisp " .. buf.Path, true, true)
    elseif buf:FileType() == "lua" then
        HandleShellCommand("lua " .. buf.Path, true, true)
    end
end

Than I run appropriate program using shortcut:
"Alt-r": "Save,runner.mode1"

Having scrollable output directly in micro pane would be perfect. It works particularly when I set openTerm param to false but whole output is in single line (in command line)

As a bonus horizontal or vertical orientation of the output pane would be configurable.

Start by reading the runner plugin example, especially HandleShellCommand and the openTerm behavior, then inspect how micro currently displays command output. Done would mean a scrollable output pane integrated into micro, with configurable horizontal or vertical orientation, without switching to a terminal.
