    The Windows GUI is impossible – doesn't have a standard "Browse…" button, cannot open through dropping on window or shortcut, has to do it in its own dysfunctional way.

    I have to give this a low mark due to limited functionality. If you open an e-Book, you cannot simply close it to open a different eBook. You must close Cool Reader, reopen Cool Reader and select a different eBook. When you select a drive letter to navigate, there is no vertical scroll bar to enable one the ability to scroll down the folder list and thereby select a specific folder. It appears that the author presumes that there will be only a short list of folders. It is not possible to change the e-book folder, again, the author assumes that all ones e-books will be located in the user/download folder and disregards users who set up their systems in a logical, efficient way that enables them to work better.

    The Windows/Linux GUI is very inconvenient, lacks common functions, is buggy and generally looks like an afterthought. The update schedule for non-Android versions is lacking too.
