So just wondering howcome FFG doesn't make a digital version of the game to support the physical copy?

I applaud the fans who have made varying successful attempts, but something official with great UI design will be nice.

We don't know how far FFG's license agreement extends (remember that Netrunner isn't owned by FFG). Also timing windows would make any online implementation potentially awkward, as we already see with the fan-created versions. I'm sure it's something that they've looked at, but there are often hidden reasons why something that seems like an obviously good idea doesn't happen.
