With the new Epic Launcher making the rounds... I'm really glad they are working on this, and aiming to improve it. The old one's been really bad for ages now. If you're an enthusiast and enjoy bug testing and reporting issues, awesome, go for it! But... if you're a developer, I'd advise staying away, for now. The new launcher doesn't pick up your UE projects outside the default directory, it also removed the "UnrealVersionSelector.exe", which is what is used for selecting the correct UE version when a .uproject is opened. Means you have to manually select the unreal engine again every time you open a project that may be in a different version. Some users are reporting that going back to the current/legacy launcher also removes your UE installs. I'll admit that the front-end is sick, buttery smooth, that's a huge step forward. But we're developers. We don't have time to beta test. We need robust software that's been tested. We have work to get done.
