KNOWN ISSUES ON KIT KAT
=======================
In Kit Kat, due to Google changed the webview engine with Chrome which has many bugs and compatibility issues. Some of features is not working. I'm working to find work around of those issues.

1. Reflow function is broken for some CHM file. So you may need to scroll left/right to view the pages. After latest upgrade 4.4.2, seems Google partially fixed this issue. So some of the file reflow works again, but not all.

2. Set the zoom level function is not working properly, so if you changed the zoom level, when switch to different page, the zoom level will be reset. After 4.4.2 upgrade, seems Google is trying to fix this issue. so now the zoom level is persisted. But I notice a new issue, for certain file, once zoom in, you can't zoom out to original level, the work around, is to "clear history" from scratch.

PERMISSION REQUIRED
====================
Internet Access Permission: to open external link to internet embedded in some CHM files.

Please help to leave a rating if you like it.

Please make sure to send me a email if there's any issue, I'll try to find a solution asap. Just leaving a comments on Play or just send a message on crash report won't help as I have no way to communicate back so I can't know the details for trouble shooting.

FAQs
====
1. Can't see the menu buttons to enable all the functions.

In Android 4.0 and above, the menu button is a list of 3 vertical dots on the right-bottom side of the screen.

2 when clicking link on the content page, It has lag in response in certain devices.

As content page is an HTML page, when you click a link, the browser sometime will treat it as pan event instead of click event if you hold you finger a little bit longer on screen, in that case browser won't open the link. So the solution is make sure to click very briefly, don't touch screen for longer time.
