I would like a new function

To whom it may concern

I am using Adobe PDF Reader for Android devices usefully (Especially with NEXUS 7,  LG G2)

However, I have trouble seeing PDF files. I use a touch pen very often, but the screen recognize it as double touch often.

So, Its size often becomes bigger or smaller, which I do not want.

So does it when I use fingers sometimes.

I would like a new function to fix the size of screen with one icon outside of the pdf document.

I don't know whether many people have the same trouble, but I think it is essential function for convenient using.

Please take account of this.

Thank you for reading my poor English writing.
