Pre-sizes spoiler images, shows thumbnail (original on hover, or blurred/unblurred on hover), with dynamic settings updates via SettingsTabManager.
This script allows you to see spoilered thumbnails on 8chan.moe/se by simply hovering your mouse over them.
You can choose between the default spoiler thumbnail, or blurred thumbnails.
The amount of blur is configurable with a slider.
If you only want blur, but no hover preview, there is an option to disable it.
Settings can be changed by installing STM.
