idarling does not support the IDA undo (CTRL+Z)

[saidelike]

Using the undo may break the use of idarling. Indeed idarling does not detect the undo was made and hence does not propagate it. For instance if you are creating a structure and cancel an operation such as creating a field, the deletion of the field won't be propagated and everything that depends on this structure will be broken

Thanks to @Cawottexit1 for reporting it.
