When I'm debugging network related issues, I often find that I want to see more of the resource details, for example when a header field has a long name or value. Unfortunately, the left and right side panes in the network panel have a limit as to how large they can get based on the size of the window. This can make it impossible to see the full details of a given request unless the window is made very large. To make it even worse, the tables for Request and Response Headers don't allow the columns to be resized. It would be very nice to be able to resize these arbitrarily.

I want to move some of those details out of the sidebar for exactly this reason.
Correct. I don't think the solution to this problem is allowing sidebars to expand to any size, but more likely putting the data in a better place (a Content View) instead of the cramped sidebar. We've had a number of ideas here that we want to implement soon.
Looking forward to seeing it addressed! Thanks for the update!
