When I am working on an existing show in DMXC3 the first thing I do after launching the software is to open the project that I am working on.
I find it annoying that the "Save project?" dialogue box pops up even though it is just the default empty project so there is nothing that needs to be saved. I know it's only a single click to get rid of it, but it's just an unnecessary obstacle
I think it would be a good idea in the next version of DMXC3 to only show the "Save project?" dialogue if something has been changed since launching the software.
