Log
The log maintains a record of all transactions applied to the project graph. This allows the following:
Undo
Logged transactions can be reversed, allowing the system to perform an “undo” operation on previous changes.
Redo
The log also keeps track of transactions that have been undone, enabling you to “redo” them if needed. Undo and redo operations can be performed in sequence (a “chain”), but once a new command is executed, the chain of possible redos is cleared. Thus, it is possible to re apply the transactions previously “undone”. Yet, one a new transaction is performed (running a new RGG function, applying a modification through the attribute editor, adding an object through the menu, …) the chain of transaction do not lead to the “redo” anymore. Thus, it is not possible to “undo” > apply new > “redo”.
