Rated 3 out of 5 stars
There are two missing improvements.
1. When Checking long text file, scroll height is limited, somehow. The contents of the file, however, continues in one long long line.
Example of long text filte: http://pgl.yoyo.org/as/serverlist.php?showintro=0;hostformat=hosts
2. Too many clicking to set regions.
Although, I prefer this to similar Update Scanner.
Continue developing & fabulous work!
