Good overall but missing key feature and has annoying bug

I have been using iSnap now for several months within Mavericks.
In general I like it.
It effectively moves windows to the top, bottom, left, right, or four corners of my single screen.
There are two improvements I think would make this the ideal free app for snapping windows.

First, it must allow for changing the keybindings.
Second, with certain applications, if I attempt to highlight text using the mouse, the window resizes. I have noticed this with Chrome as well as less generally used apps like SQL Workbench, SQL Developer, and GNU Emacs.

If you don’t mind these 2 issues, then this is a great windows snapper for you.
