Blacklist unwanted applications in settings

[khvMX]

Would be a killer-feature! I've seen that most of the issues can actually be solved by users if there was an option to block the notifications from unwanted applications. Some GUI element representing the list with "add", "modify", and "remove" buttons in the extension settings would suffice.
I believe it's feasible due to this quote from bergschreck:

Best notification extension. I tried 2 others, but they didn't work with evolution mail. This one notifies everything, a little bit too much. ;-) But it is easy to blacklist unwanted applications in source code. To blacklist iceweasel and owncloud, I changed function _hasNotifications the following way: this._hasNotifications = function(source) { var title=source.title.toLowerCase(); if (title == 'iceweasel' || title == 'owncloud') return false; if (source._counterBin.visible && source._counterLabel.get_text() != '0') { return true; } for (let n = 0; n < source.notifications.length; n++) { if (!source.notifications[n].resident) { // Do not alert resident notifications (like Rhythmbox ones) return true; } } return false; }
