Just to clarify, to use it, do you add all your coin addresses, and it will update your current amount there? Anything that requires download is sketchy to me, and for that I wouldn't use it. Why not change it to an online site instead? I don't see why a simple tool like this needs to be downloaded.
Would like it if this has notifications and linkable with pushbullet so that your phone can get updates too.

@EXtremeAEX Thank you for the reply and your concern about security !
First I was going to make a web application, what happen and since I been working has developer for quite some years is that the web services online work like the following example:
there are ledger limit requests per internet address, which will compromise the application functionality. Which means that some errors could happen for "excess requests" if the web application get for example more than 1000 users
So what I did was convert the web application into a "stand alone version" running locally, which is basically a build in "Apache Server with PHP7" running the script. I encrypt only the PHP code because of the copyrights, however the front-end is made in HTML5 (bootstrap 3) and jQuery, which means you can personalize in anyway you want, with languages or add-in features, since the code is a RESTful API of a Tool I also made called PandIX (
https://bitbucket.org/CesarGrancho/pandix/ ) which is open source and anyone can use it
And the last part was the exchange accounts, since it's so sensitive data it was really dangerous to kept that information online, also there are some exchanges sites that do not allow to use that information, so the user consent and is owner of his own security.
Regarding notifications, what would be great for you ? Try to clarify the best way, you can even use paint with arrows and writings!

Thanks
