Anyway yet (or future product suggestion) - of getting transparency back on Windows 10 title bars.
This guy has done it with Glass8 ( http://www.glass8.eu/ ) but it's 'donation' only and you are not guaranteed the product or any number of keys for the software.
If it was built into Window Blinds - so that you could select the default theme and adjust the transparency, that would be great.
Tonnes of people on the Glass8 forums are interested in this, so definitely a worthwhile project financially I would have thought.
