Just reporting some things I found.
68 installed itself today and the colour picker in the developer tools has changed. This new version doesn’t allow the colour to be selected and modified in real time as it did before… i.e. it’s not behaving like a picker. Now one has to close the picker, reopen it, make a choice, and then do it all over again for every variation. It’s like the options in the picker only work once.
An additional issue I notice is that it is now more difficult to insert a new CSS style in the right hand column of the dev tools. One could previously click anywhere to the right of the selector or declarations and it would enter a new one. Now one has to click around trying to find the spot.
