futurity | simple tool to convert plain old Java Future

Have been working through this slickR problem for a while. I would greatly appreciate any input or fresh perspectives on how to resolve this issue or different ways to approach a solution.

There are two issues I've been working through:

The first I think can be solved using CSS, which I am not super familiar with, slickR seems to be creating multiple divs when the 'obj' is updated through the use of input$series. This is undesirable since it relocates the most recent div lower on the page. I tried using javascript, which I am also not very familiar with, to destroy the old slick using an observe event. Bonus points for a simple solution for that issue.

The main issue I am working to resolve is that I would like to convert the dots to images and have them update dynamically as each series is selected. The goal here is that I would like to have a larger image displayed above and a series of 'thumbnails' displayed below so that the user can have some idea of what each photo looks like without having to scroll through every image in the carousel.

My app is much more complicated than this example, but I am using slickR since it has a convenient way to access the current, active, and center slides, which I am using to filter an additional dataframe to render the display of information regarding each active/centered image in the carousel.

Here is an example which demonstrates both issues:
