My current campaigns themes.
Call of Cthulhu Attachment 58971
Alien Attachment 58972
FBI Attachment 58973
I use modified tower icons, assets icons and GM chat icons (if interested you can download my free extensions on the forge for Alien and Cthulhu and modifie the pictures to fit your campaign like I did for my FBI campaign.
I use two 2560X1440 screens, side by side in full screen using this command for the exe: "C:\Program Files\SmiteWorks\Fantasy Grounds\FantasyGrounds.exe" -popupwindow -screen-width 5120 -screen-height 1440
It makes me a lot of space for Discord and Kenku FM that I keep in front of FGU using Turbotop free software.
I hope this could help you in some way for your campaigns.
