Ok, bought the application and it's pretty decent but some essential function are missing and it has many design problems. Here some suggestions for the author:
Go to page - Last and first page are useful but most time you need to go to other pages
Scale factor (number & fit to page options) - it's stupid that the app resize every single page to the default value, in a comics reader a customization of this parameter is essential
Gesture - tap to show info, slide to change page, in a similar way to comix app.
Download in background - or at least under the lockscreen. Because it's very frustrating when the screen locks and you have to restart the download, even more if you are in 3g.
Log the errors - this app is overall stable (much more than comix), but i had 2 or 3 crashes. You need to print the error message so we can tell you the reason of the error.
Title too big - if someone download your app from the store we can suppose he knows it's name. So why in the main menu the title of the app take 1/3 of the screen?! Make it smaller and use the Space better(see below).
SkyDrive menu inusable - it's a mess, font to big, label to short. In vertical orientation you can see 1, max 2 items. With the orrizzontal neither 1. Use the Space better.
progress bar during decompresion - when the download from SkyDrive ends the Phone freeze for 4-5 seconds. I suppose you are moving\decompressing the file. For a user is bad to see an app freezzed, so do that operation in background and put a progress bar
I don't give a feedback for this app, if have to do now it will be 2/5, but this app has great potential. So i want to wait to see if you can fix it.
