So I've got the SafariStand plugin installed, and I love it. It especially works great with the History Flow feature, which I use all the time to browse my history. Problem here is that I started looking through my hard drive for some old files to delete, when I found the folder that stores the thumbnails for History Flow (~/Library/Caches/SafariStand/thumbnail.noindex/). It had kept the thumbnails in there since the day I installed the plugin! A few gigs of data were being used up by these really outdated items of history. So my question is, does anyone know of a way to have these items be deleted after a certain period of time? It seems that Safari's option to erase your history over a set amount of time has no effect on the files stored within this folder. Any ideas? Thanks.
