I would like to request a mod that would expand the side bar to show more items, and information.
Essentially just in general make it wider for much higher resolution screens.
Edit: Increase the number of columns when looking at Logistics. 
Here are two screen shots to show what currently happens on UI size change(Which doesn't help.
Large UI on High res screen
Small UI on High res screen
My screen resolution is 2560x1440, and when playing I like a small UI, however in both circumstances, Bob's mods adds so much stuff that my Logistics network goes beyond the boundary of my main screen. I would love to see a mod for this, that could be enabled only on one client, without affecting the server, or multiplayer groups. This is a great idea for people with high res screens, but probably not for 1920 or lower.
