A recommended mod list for the Seamless World update that expands the game without straying far from the vanilla experience or balance. Mostly QoL improvements and fixes.

QoL Additions (game balance friendly):
Pause Game - Adds game pausing in single player.
Digital Clock Date - In game text with date/time.
Command Handler - Adds some chat commands, mostly search functions, nothing balance breaking.
Display Skill Levels from Equip - Displays skill levels added from your equips, only passive skills gain levels.

QoL Improvements (these slightly affect game balance and make it a little easier):
BigChests - Bigger chests
BigStacks - Bigger item stacks
SprintFix - E no longer cancels your sprint.
BasicToolFix - Tools no longer get you stuck in a forward animation, makes gathering resources less of a pain.
Quality of Life - Gives you a bunch of additional command handler chat toggle commands, for things like less magic shield sfx, remove character outline, etc. Really great mod, I highly suggest reading the description to get familiar with the toggles.

*No inventory mod since that would defeat the point of doing objectives to expand it. I feel big chests is a little too cheaty too but the default chests are just way too small. Hopefully I can replace this mod with something in the middle ground soon.

Fixes:
Drop Items Force Stack - Improves game performance a lot by having items stack when dropped near each other
UnderGroundPicker - Automatically gives back and building items to your inventory if they fall below the ground.
