+=====
+ * **Find & Preview**. Instead of merely telling you where your search phrase has been found, it actually shows it too. 
+ * **No daemons**. As other solutions are prone to have annoying daemons running that eat system resources away, this solution should make do without daemons if possible.

+ * **GUI & CLI**. Provide CLI interfaces and GUI interfaces
