Block unwanted Toast notifications. Presently there is no functional UI. In order to block stuff, you need to make a file named whatever the app's package name is (ie com.egingell.untoasted) in /sdcard/UnToasted and put the text you want to block. Multiple lines in the same file will get used individually so you can block multiple Toasts from the same app. You can also use regular expressions.
Looks like the code on github may be outdated. The code here was last updated 3 days ago, while the module was updated in the repo yesterday. Keep in mind git commit only commits changes locally.
