One thing which really frustrates me in Chrome DevTools* is when you are inspecting a dom object,
all the null default properties are listed so you have to scroll thru them all, just to find the interesting properties.
There is a bug about improving this, it’s currently “archived” but it would be great if you could star the issue and nudge any of your fellow web developers to also star this issue
https://bugs.chromium.org/p/chromium/issues/detail?id=508056
*if you use chrome on windows, you might have noticed that the window title for devtools was recently shortened so you get to see a little of the url being inspected in the task bar… you can blame me for asking for that change!
