Any way of scripting this to automate button clicks etc? I use PhantomJS for this now but found it to be incredibly unstable for complex pages.

But ultimately selenium and webdriver.io will do a better job at this

Also checkout https://github.com/cyrus-and/chrome-remote-interface for an easy way to fully control those headless instances

Please let this be capable of generating PDFs from HTML from the command line.

FWIW, you can do that now, using phantomjs (which is chrome) http://phantomjs.org/screen-capture.html

Also with https://wkhtmltopdf.org/ and http://pandoc.org/

Any chance for webgl here? Would be nice for automatic screenshots and webgl tests.

What does this mean for Electron and other apps that depend on Electron?

Any idea if you can configure the page DPI with this API?

The feature I was most interested in when they announced this last year was virtual time. The Developer Resources link has it listed (https://chromium.googlesource.com/chromium/src/+/lkgr/headle...) but it's a broken link, unfortunately.

Mostly, I'd like to know how the control of the virtual time system would be exposed. Would it be through the C++ API, or could it be made available through the debugging protocol?

Not sure of your exact use-case, but mPDF does this well.
