This is only semi-portable. Separate instances "talk" to each other.

Aren't portable apps completely stand-alone? IOW, they don't store or automatically read configuration information from outside their own directories? That's not to say they can't see files outside their confines, or even optionally import settings.

If by default, a portable app stays within it's boundaries, then it should be possible to one instance of a portable app on one flash drive and another instance of the same portable app on a second flash drive. That is certainly the assumption many users of portable apps have. They should be able to open the app on a computer where someone else previously opened another instance of the app without interference between the two. Of course, if you can have them on different flash drives, you should likewise be able to have two instances of the same portable app side by side. They don't extend beyond their directory borders, right?

Maybe you wouldn't be able to run both instances at the same time, but you should be able to close one and open the other (with completely different settings) and neither would know about the other.

If all that is true, then this isn't portable. I need to be able to use GitHubDesktop under two different accounts. I thought this "portable" app would resolve that problem. However, while I can create two instances of GitHubDesktop, if I sign into one, then close it and open the other, it immediately signs me in as the first account. They are cross-talking.

Thus, if I put this GitHubDesktop Portable on a flash drive and try to use it on a computer where another user has already done the same, I will get their GitHub profile. That's not good! Also, not portable!!
