+### Disable the credits indicator smooth transition
+
+- In vanilla, the Credits Indicator has a smooth transition effect when the displayed credit value approaches the actual credit value. Now you can disable this effect, allowing the change step to always follow the value of [`CreditsIndicator.MaxStep`](User-Interface.md#customize-the-step-limit-of-the-credits-indicator).
+
+In `uimd.ini`:
+```ini
+[Sidebar]
+CreditsIndicator.Smooth=true  ; boolean
+```
+
+```{hint}
+For example, if you want to make the credits update immediately without a transition process by setting `CreditsIndicator.MaxStep=0`, then you should also set `CreditsIndicator.Smooth=false`; otherwise, the displayed credit value will still change in the form of an exponential approximation function.
+```

 ### Flashing Technos on selecting
 
 - Selecting technos, controlled by player, now may show a flash effect by setting `SelectionFlashDuration` parameter higher than 0.
