Edit operation architecture for saving of arbitrary information

It will be useful to save information about operations that is not essential to their execution, but can be used for diagnostics and/or suggestions. The operation architecture should be extended to allow for the collection of information such as:

• Execution time of operations, for calculating averages or suggesting extensions
• Additional information required by/for plugin operations
• Operation list overlap for diagnostics

Estimate includes investigation of current setup, examining plugins where additional information may be required, further development, and testing.
