It is often useful to display a progress bar showing the state of a task. `MG_Progress` can easily be used to display a progress bar, percent completion, and estimated time to completion. As a simple example, let's pretend to load 100 items (while actually just waiting a bit):
foreach i, mg_progress(indgen(100), title='Loading') do wait, 0.1
The above line produces the following output:
Code for [mg_progress__define] is on GitHub (you will need [mg_statusline] also). See the code docs for the many other options that can be used with `MG_Progress` like dealing with a list of items that don't all take equal time and customizing the display.
