So a recent poster to the FB group noted that if you go to a module that is inactive and go directly to the preset menu and create a new preset and give it a name and save it to auto apply to all images that the result is a no-op. Clicking the preset menu does not by default activate the module and if you make no changes to the module it is also not activated however you are able to save that as an autopreset. I think he was under the impression that this would for example add dehaze with the default settings.
I think this might be rare as generally you are altering the default to create a preset or working with the module in an activated state nevertheless the result is an entry for the module that appears in the history stack which isn’t much use as it was never activated so really stepping back to it doesn’t achieve anything and selecting steps in the history does not reposition you to the module in the the editing pane or anything so its not really a place holder. THere may be a use case for this behaviour but I could not think of one but perhaps there is a reason that it is set this way. In any case it caused confusion for this user.
My comments to him were…
“Thinking about this a bit more…this may be a bug or have a use case I cannot think of. I was actually talking about styles in my previous comments to you and not presets. They will capture the state of the module so you can add a style that has a number of modules…it might be your default workflow with your common settings defined for each however they can all be in the inactive state…now as you edit you sequentially activate them or maybe you have some active but say noise reduction or some others initially inactive but ready to be applied by simply activating them with your settings and not the default ones for that module. So there is a use case here. But i tried your experience by going directly to a module and asking it to be auto applied without activating it or setting any parameters. As a result it will add the module to the the history stack but it is not activated and no edit is ever applied. I would assume you thought it would be applied with the defaults?? Most people when saving a preset will make some adjustment so this will likely never happen but in your case your initial steps gave you a null result… As I said there might be a use case for that setup but I think its just that for the most part not many if any have created the auto preset using your steps…”
