This is a sidecar plugin to add features to the otherwise standalone TC Topic List Previews:

• 'actions’ (bookmarking and liking from Topic List)
• Thumbnail Picker in the Topic Meta Editor.
• Optionally suppresses links in excerpts to make them look a lot better

This sidecar also includes some experimental features:

• Colourisation of background based on dominant colour of the thumbnail
• Processing of the thumbnails to remove any black borders (critical to determining the best dominant colour).
• Option to recreate thumbnails on rebuild of Post to allow you to quickly manage border elimination.

You must have the Theme Component installed for it to work/be useful
