My primary complaint: in my opinion, Impulse (and SDC) should not show the serial numbers for the user's products. It is far too easy for someone, at let's say a LAN party, to launch the application and write down all of a person's codes. I also don't think it's a great idea for Stardock to be asking for these numbers if a user has an account problem. Most other companies never ask for this information, because it's far too easy for it to be manipulated or stolen by an outside source during transmission (or for someone to impersonate Stardock and pry it out of someone).
Here's the things that are wonky for me in Impulse:
It recognizes my GalCiv2 and SoaSE just fine, but for GalCiv1 and AP it finds versions that are not available via SDC. Via SDC I am at 1.22.102 and 1.52b.014 (respectively), and Impulse wants to upgrade to 1.22.104 and 1.52b.015.
Impulse is not finding my Dark Avatar or Twilight of the Armor at all. For both it is also seeing versions that are not available on SDC. Via SDC I am at 1.80g.100 and 0.97[b].001 (respectively) and Impulse wants to install 1.80g.102 and 0.98[b].010.
Please make an option to have smaller icons, plus display programs in list mode instead. As is the entire application takes up too much space.
I'm also surprised to see so few options for Preferences. There's a lot more I can tweak with SDC.
The application is looking modern, but right now it has a long way to go to properly compete. I appreciate the effort, but besides looks, I can't see what this is offering over SDC. Right now it seems to be a lot LESS powerful than SDC.
Sorry for the criticism, but I do overall love what Stardock stands for, and am pushing for you guys to get better. Good luck,
