When I am searching for domains or keywords, I always find myself having to copy/paste and find my notepad document dozens of times - it became annoying. I hired a software developer to create a desktop application that looks like notepad+ at first glance, but as long as it's open you can highlight text and simply press CTRL+C+P (Copy and Push) to send that text to the notepad without ever leaving the screen. It has a full text editor with line numbers - and you can set how many line breaks in between the pasted text. I will give this to anyone for free - just send me a PM for the download link. I find it VERY useful and time saving.
