Settings

Setting	Type	Default	Description
Undo Steps	int	100	Maximum number of actions kept in the undo history

Undo Steps

Controls how many actions Plinken keeps in the undo/redo history. A higher number allows you to undo further back but uses more memory.

Select from the dropdown:

Value	Description
20	Minimal — low memory usage
50	Light — suitable for simple sessions
100	Default — good balance of depth and memory
200	Extended — for complex editing sessions
500	Deep — large projects with many edits
1000	Unlimited — keeps virtually all actions

When to Adjust

• Increase if you frequently need to undo many steps, or work on complex projects with lots of small edits.
• Decrease if you’re working on a memory-constrained system or with very large projects.
