You can drop a mail any time you want with Thanks/Suggestions/Questions/Curses. I welcome all/any kind of feedback.
If you use Silencify your are my customer and you have full rights to complain about it as much rights I have to brag about it.
On serious note, I would definately keep up with resolving any issues you face or adding any feature you request. I would just like to clarify, every effort has been made while coding this App that it does no suck on your battery, So before requesting any new feature think if it is really required and wont affect your battery life, if you are not sure do let me know I would be glad to figure out.
