Sessionkeeper - Bootstrap modal backend progress bar

Hi! I think the progressbar / countdown bar in the bakcend (Bootrap modal) is not showing correctly. It's all red and there are no 'moving' parts that show the coountdown.. See attached screenshot.

Joomla 3.8.7
Session Keeper 3.1.0

I see this error in the browser console:

Uncaught TypeError: root.newCountdown is not a function
at SessionKeeper.modalWarning (sessionkeeper.min.js?72894a6f67ea3cbf71e3dce3ab208a80:
at SessionKeeper.displayWarning (sessionkeeper.min.js?72894a6f67ea3cbf71e3dce3ab208a80:6)
at sessionkeeper.min.js?72894a6f67ea3cbf71e3dce3ab208a80:4

I was so focused on the alternate modal, I messed up the regular modal!

Version 3.1.1 available now, your updater should see it in 12 minutes or so.

Hi Michael, thanks for the new version! I see it indeed works better now in the backend. I do have one remark about the layout of the bootsprap modal in the backend: The modal-body could use some padding on the left and right. Is this something you can add/change?

To make it look more like this:

I'll put a 10 px left/right margin in the next version
