app_showcase(app_url, img_url, title, subtitle, label = NULL,
  drop = NULL, height = 200, min_width = 300, max_width = 400,
  col_width = 4, img_style = NULL, new_window = TRUE)

`app_url`	character vector of app urls.
`img_url`	character vector of image urls, same length as `app_url`.
`title`	character, titles displayed on image links during mouseover.
`subtitle`	character, subtitles displayed on image link during mouseover.
`label`	character or `NULL`, optional fixed label place above an image panel. See details.
`drop`	character vector of any apps to exclude from showcase. Useful for programmed app lists that may include self.
`height`	numeric, height in pixels.
`min_width`	numeric, minimum width in pixels.
`max_width`	numeric, maximum width in pixels.
`col_width`	integer, column width number for row, 1 through 12, defaults to 4.
`img_style`	optional style for the image component of the widget. Useful for padding in particular, e.q., `style="padding:10px;"`. Defaults to `NULL`. See details. If length is one, is repeated for length of `app_url`.
`new_window`	logical, open the link in a new browser window. Defaults to `TRUE`.

Despite being named for this apputils context, app_showcase can be applied to other types of content.

The image padding argument is useful when multiple source images have different amounts of margin space embedded in them and you need them to match each other better, or when you need padding around an image that includes no margin around it. For image padding, use a vector of length one or length equal to the length of app_url.

If label is not NULL, it must be a vector with a label for every image link. To force empty labels among non-empty labels, use "". E.g., label = c("A", "", "C"). label can be styled by using html, e.g., label = h4("Top Title").
