1. No option to select RAM only cache during installation. I entered zero for the size, which it allowed, but after rebooting, there was a 512MB file called RETURNIL.RVS in C:\RETURNIL\ 2. The main window does not have a taskbar button when visible. I know the tray icon can be used to bring the window to the front, but I often have lots of windows open, and a taskbar button gives me a quick indication as to which windows are open. Can you add an option so people who want a taskbar button can have one. 3) No option in the main window to only use a RAM cache.
