Peculiar behavior loading a 3mf file  

Peculiar behavior loading a 3mf file

If I open Prusa Slicer by clicking at he software link and then load a 3mf file, the Save Project menu option is grayed as it should be. But if I open it by double clicking to a 3mf file, this option is not grayed. And if I am going to close the software without applying any change, I am asked to save the project.

So my question is if something is changed in the project when I load it by double clicking to the 3mf file, or showing the project as modified is a software bug. This is very important, because if I slice a project loaded by this action, I must be sure that all saved parameters will be used and nothing is modified.

I also would like to ask  an other option about parameters' changes of a project. Loading a 3mf file from the Slicer menu and then changing one or more parameters, the Save Project menu option is available. If I change again the parameters to the project initial values, the Save Project menu option is grayed, meaning the software is keeping track for the changes that have being applied (and this is a correct behavior). 

Unfortunately there is not any indication if a parameter is changed from the initial project value. We can see if a parameter is different from Default value (by the Locked / Unlocked image), or if it is different from the last saved Preset value (by the Back arrow). It would be useful if we had an indication (and a "reset" option) for each parameter different from the project saved value.
