Uto equalize splits, know that modules will not be distributed across the entire dashboard space. They will equalize to the portion that they were split from. For example: if the dashboard is split in half, then one of those halves is split into 2 modules, the equalization hotkey will change the distribution of space to 50% for the first module, then 25% and 25% for the next two.
