Please make lazy loading of the files a setting.

The ability was briefly enabled but removed in 3.5.1, unfortunately.

In most cases, we don't need to fully reload all the PDF from a session until we want to actually read it a file.

This should work like most modern browsers (and even Notepad++ works this way).

It would make opening Sumatra so much faster.

A setting for it would give us the choice of which compromise each user prefers.

Thank you
