QGIS now supports the capability to configure the default values for GUI tools within the QGIS Processing framework using parameters specified in the QGIS.ini settings file.
This allows for the configuration of user-specific or organization-wide default values for certain algorithms. For example, to set the default value of the GRID_SIZE (precision) parameter on the intersection algorithm, the following configuration may be added to the QGIS/QGIS3.ini in the active user profile directory root:
[Processing] DefaultGuiParam\native%3Aintersection\GRID_SIZE=0.01
When a user with this configuration opens the relevant toolbox to execute an algorithm, the default value will be specified for them automatically.
