When it comes to mods, I’m trying to keep mostly vanilla. As mentioned before RimFridge is my one non-UI related mod that does affect game balance a bit.
The UI mods I’ve found and would recommend are:
Color Coded Mood Bar - You can see how in my screenshots my guys icons at the top are colored. Makes it much easier to tell at a glance who needs cheering up.
Interaction Bubbles - Puts what people say to each other in little speech bubbles. This one I really love. It exposes what would normally be missed most of the time as it is tucked away in the social tab.
RimHUD - A big upgrade to the UI panel that shows when someone is selected. You can see this in my recent screenshots as well. Shows all kinds of relevant info. The content and things like font sizes can be customized.
More Harvest Designators! - While the trick I’ve mentioned about setting a growing zone to no sowing in order to harvest only fully grow trees works well enough, this mod adds proper options under the orders menu to harvest only mature trees or plants.
Better Pawn Control - This one allows you to set modes that incorporate things under the restrict and assign panels like clothing sets or allowed areas. I currently use to manage animal areas with one click. I created a “red alert” mode and a “normal” mode. In red alert all animals go into the “yard” which is within the walls. In normal mode some go to “pasture” which is the yard plus grassy areas outside the walls and those animals that can haul have their own area that covers everything but food storage I don’t want them to eat. You can also do things like make “red alert” mode have certain guys switch clothing profiles in order to armor up.
Work Tab - An upgrade to the work tab that has things like 1-9 instead of 1-4 for priorities and breakdowns of the work types so you can do things like set a different sowing and harvest priority.
Medical Tab - A new tab that gives a summary of all the colonists medical conditions. Or in the late game I like to call it the “who needs another bionic limb” tab.
