Project Status: Disabled
Hi, Sven and all. 
I know I asked a similar Q in the past...
But it still seems to make sense.
I know i can just disable engines or ways of getting targets.
SO that is already doable, but in the main project pane you won't know that is the case.
But this could quickly do the same without having to mess with setting you may want to retain.
This is all so we don't accidentally run a project for whatever reason we may not want to.

I am not sure I fully understand your question, so forgive me if my suggestion is not what you are hoping for.
If there are some engines you want to permanently disable, why not just delete the engine in: C:\Program Files (x86)\GSA Search Engine Ranker\Engines
But i think u will need to do it after every update
Or, better yet, just move it to a folder elsewhere as a backup.
