Hello, Epic. Just some feedback on your Dev kit interface inside the launcher and in the Editor it’s self.
When you are downloading files from the Marketplace tab, in order to view download progress or the file you have to navigate through the marketplace and find it again. This seems weird. Maybe you should make the list of files on the left hand side of the launcher link to the file locations on the marketplace, or have a feature where you can hover over the file name in the main page of the launcher and see relevant information, like download progress, date created, etc (drop down list?).
Additionally, inside the editor there is no way to manage your project files whatsoever, besides opening one or creating another. Maybe you should add a file manager that can safely remove, rename, or otherwise alter project files in case you make a huge mistake, and are at a loss on how to fix it (In the case of blueprints, people who are inexperienced with the editor, coding in general, Microsoft VS or game design could benefit from a bit of a “reset” button, to help manage data efficiency).
That’s all I have for right now, but I expect to have more in the future. It’s such an honor to be one of the first people to develop for UE4. Thank you for your time.
