If the developers will rework Epic games launcher, maybe it be better to immediately create an interactive version for players in the main. Something like this (on the example of the MWO launcher)
After registration this launcher load all games. Games there looks like small video frames showing gameplay process and videos from scenes of this selected game. Video Frames moving around the horizontal circle position, relative to the direction of the mouse cursor. This window has the main information about account name, MC like from MWO currency (only one for all games), show some descriptions and some current information about this selected game. If press Select a game button, this window unloads from memory and run (or install-client) special game window there shown everything together with the store and all services and of course Play button. The main launcher window has standard size and look, but current selected game windows has its specific look related this game. Size and design is always different in each game.
Something like shown on this picture, the current launcher window is a heavy program that contains everything and is very narrow. If the game video frames move around in a circle there can be a large number of games and they do not interfere with each other. Also remembering the last game selection and loading with the display of this game. If game got new version this written under video frame, but only for the two nearest video frames on the left and right of the game in center, but game title shown only for left, center and right video frames. The Games tab will be selected by default after installing launcher.
