Changing the undo limits
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 take up about 5-10 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.
