Great outliner for the css
I am uninstalling because of this new colored blocks layout. Please bring back the old version.
felt it is good to use
New update is too bad. Whats with all the sharp colors. I can hardly see any text. Please rollback the changes.
Ctrl key does not work, trash.
Doesn't work anymore
New update is trash. Bring back the old version
The "Ctrl" key option doesn't work in this new update. Please fix.
I think Angela should provide an alternative to this Chrome pesticide extension; the old version was much better.
This is nothing more than trash now. This used to allow its users to see the div and all necessary info once the users hover on the boxes. But now, not only does that function stop working, but also the background colors make an eyesore to it.
