some functions will make the tool better

[sickneet]

if the pip window is not very big,I can't see the text on the picture.
I want to use full-screen pip,but I can't see the text on it. So, I hope to have the function of zooming in and out in pip.
Also, I want to have a function of sliding the page on pip so that I don't need to swtich to the program window and slide the page and back to my work.
Finally, I hope it can open muti-windows rather than one window.

I don't know the difficulty of these functions realization, but I do hope this tool be better.
Thank you!

Thanks for the ideas, I will fix the issue #3, and I will work on it after.
I have kept the PiP-Tool without too many buttons, options ... to make it easiest to use as possible. But, yes, I think it will possible to implement these functionalities.
