I’ve recently adopted Keypirinha (Windows keyboard launcher, similar in function to Cortana). It extends to several search and databases, and free to use. I could envision using it in conjunction with Confidential, i.e. with the add-on to it, one could parse the Confidential tags to launch, rather than just filenames…over add the same search as you type; benefit to “me” would be one launcher, with a filter for things I’ve tagged. Keypirinha has addons for other similar software/services like Pinboard, Filezilla, “Everything” search, Pinterest…to catalog.
I posted this in the Tabbles forum too while browsing for information on the API.
