I have only just started using this app. I like it so far, but I think I will wait until I have a little more experience with it before I give it a rating. However, I have a few comments to make:

1) The interface is, in some ways, a little weird. For example, PAGE_UP and PAGE_DOWN should be inverses of each other. (That is, one should undo the effect of the other.) In fact, PAGE_UP goes back a screen but PAGE_DOWN goes forward a page.

2) A nice feature would be for the window to display the name of the last file opened. For example, I am currently reading The New Avengers series with filenames The New Avengers.001.cbr, The New Avengers.002.cbr, etc. When I finish an issue, I haven't necessarily kept mental track of which issue in the series I have just finished. If the window displayed this information, I could select the next issue to continue reading.

2a) A *really* nice feature would be to recognize sequences like that and provide a button to open the next issue in the series.

3) "Comic Reader Pro" is a really strange name for a freeware app.
