After I installed a new game, I don’t see it added to the list of my games immediately. My current workaround is to close and quit the WeMod app from the systray, then start it again, because it scans for installed games during its start.
I miss a way to make it scan them on demand, e.g. by clicking a button or pressing the usual keyboard shortcuts of a web browser, like F5 or Ctrl+R.
