PlantStudio supports multiple undo with separate undo limits for operations that require small and large amounts of memory. This allows PlantStudio to limit the undo list more by how much memory has been used and less by the number of actions. This gives you a greater capacity for undoing.


For example, changing the rotation of a plant only requires that PlantStudio save the old rotation and the new rotation, a tiny amount of memory. But copying a whole plant, and then undoing the copy, requires that PlantStudio save the whole copied plant in memory. Plants can take up anywhere from five to hundreds of kilobytes of memory, depending on how large they are (how many leaves, stems, etc). So if your main concern in saving undoable actions is how much memory you have, this two-tiered system lets you get the longest undo list your computer can handle.

To change the absolute number of undoable actions the undo list keeps,

▪        Choose Preferences from the Edit menu in the main window. Click the Undoing tab, then change the number labeled Number of actions to keep in undo list.

To change the number of plants the undo list keeps,

▪        Choose Preferences from the Edit menu in the main window. Click the Undoing tab, then change the number labeled Number of plants to keep in undo list.

We have set the upper allowable bounds for these undo limits fairly high to give you ample options. Pay attention to how much free memory you have available (and how many other applications you have running) if you set the undo limit for plants to a high number.
