Some users may want to have a special kind of popup for some keywords present in the message (e.g. Red popup which stays indefinitely until you close it when a word "urgent" is in the message). Like in
SPARK-1596 it could be another tab in Roar settings with a name "Keyword popup", which would have same settings (colors, position, time, etc.) and a field to input keywords (comma delimited maybe). Also some users might want to only use Roar for keywords, so there could be additional setting to disable regular popups (in the same tab). Obviously it should have its own color, position and duration settings and also a text field to enter keywords (comma delimited).
