 This repository is basically a matplotlib extension using the Qt backend to create plot windows with groups of tabs, where the contents of each tab is a matplotlib figure.
 This package is essentially a replacement for pyplot; it creates and manages figures separately from pyplot, so calling `pyplot.show()` or `pyplot.pause()` will not do anything with windows created from this package.
 This package provides the functions `show_all_windows()` and `update_all_windows(delay_seconds)`, which are very similar in behavior to `show()` and `pause(interval)`, respectively, from pyplot.
