The MX Key keyboard needs an option to change how long it takes for the backlight to turn off. On the default setting it turns off so fast that it is occasionally headache-inducing and makes the backlight almost unusable (not to mention the tediousness of having to constantly wake it up). As a software developer this is especially disappointing as the fix should be extremely easy (especially when the APIs/interfaces for the logi options+ app and keyboard are already thoroughly in place) yet the keyboard has been out for 2 years and this has, as far as I can tell, also been a known complaint amongst the community for quite some time. Any seasoned software developer who is familiar with this keyboard/options+ should be able to provide a solution in less than the span of an afternoon and significantly improve the quality of this product.
