Updated for game version 1.58.63. This is intended for Legacy Edition (32-bit PC players and non-Metal Mac players) only. If you play the normal version of TS4, do not download this version.
The Sims 4 More Columns in CAS v1.9.1 for Legacy Edition
This mod increases the number of columns in CAS. Two flavours of the mod are available: 3 columns, and 4 columns.
If your game’s resolution is too low, the UI might be cut off of the screen. I don’t recommend using the 3 column flavor if your resolution is lower than 1280×720, or the 4 column flavor if your resolution is lower than 1600×900.
