Hi!
It is my first time even posting here so I hope it is at the right spot 
.
Today I was checking the activity log and I found some odd request, so I thought lets dig deeper.
If you add new columns because you want not to click on every event for some details, like the URI Path or the domain it touched, it seems that the UI is not scaling at all.
With the sidebar collapsed it is a bit better but, why not expanding the middle?
There is enough space to the left and right, make more room for expanding the center view.
Some screenshots from the expanded events.
