DEVONthink uses macOS’ Quick Look technology to support most third-party file formats on the Mac but this technology is not compatible to the web. Therefore only standard file formats (images, PDF, HTML, plain/rich text, Markdown, sheets) are currently supported by the web interface.
I understand that Quick Look itself isn’t compatible with the web.
But would it be possible to generate Quick Look previews as static images on the DEVONthink (e.g. when indexing), and display those in the web interface?
Even a simple image snapshot of the file—like what’s shown on macOS—would be very useful for browsing and identifying files remotely.
