 This a automatic deletion is a controversial decision..
What is an idea ?

 I see that they are automatically deleted from the Resources, but they are
still saved/placed on hard drive (not in .xml)
So, if a user changed size back to original, but then he again returned to
the proxy size,
re-creating proxy does not occur. The program uses the previously created
proxy files from drive.
Right ?

How about creating a separate folder for links to these proxy files on
drive ? (a folder like the folders for Labels, Clips)
This would be convenient if the user made the project, then again returned
to it after a while. He goes to the proxy folder and gets full information.
This would be convenient if with using a proxy for individual files.

What do other users think of that ?

Ok. Thanks for the explanation.

Yes. Thanks.

Just for fun, you might want to do an info/detail in the resources window

:-)Yes-yes, I see:
