I've just installed this app and it's fantastic, especially as a former Windows user!! I've been looking for something like this since I bought my Mac 2 years ago! So, thanks!
My only problem seems to be that even though it maximises on the right hand side, it always leaves about 2mm on the left hand side, even when I use it on a screen that has already been manually maximised. As it happens, this has been an issue from day dot with Safari, that whenever I open it, no matter that I have dragged it to maximise the screen in my last session, it always opens a little to the right. Any suggestions would be appreciated!
