Opening files without project manager plugin

I use QtCreator as a text editor. I enable only TextEditor and BinEditor to just edit text files, then call it from filemanager as any other program.

The issue is, you can't open file with only those 2 plugins, you also need GenericProjectManager, which makes startup really comparably slow.

But. You don't actually need GenericProjectManager, because with those 2 plugins you can first open an instance of creator, and then feed it files with qtcreator -pid. I attach a script that i use to start an instance and then open the file in it, and the profile that i use, but that relies on bash sleep, toothpicks and glue.

So, opening a file from argument on first startup should just work without project manager plugin imo, since it does on all consequent.
