40 seconds for 235 files here. Still largely annoying, I frequently 
switch projects which is basically a pain. This 235 are part of a 
project. A real one which I use, not just a test case.

Can the recent manager be disabled for projects? The files are collected 
in projects and there's the recent project list, so I don't see a need 
to add files that belong to a project to the recent files list.

To be honest, I never use the recent files feature. 11 seconds sounds 
like a dream.

Best regards.
