Still works perfectly in OSX 10.14.1 Mojave. Amazing that this 2007 software still runs fine despite all the OS changes!

Been using this for several years. It's simple but it's so useful. Love it! Glad it continues to work through the OS's.

Still works on 10.9.5, although one has to make the rulers visible with cmd-1 and cmd-2 sometimes. Have not figured out the exact behaviour. A great enhancement would be an Always-on-Top option, for e.g, aligning or positioning selections in a graphics program.

Obviously a lot of thought went into this little app. It does what it's supposed to do extremely well. I works so well, I'd have a hard time making any useful suggestion to it!

Works fine on 10.6.2. Unfortunately, as the notes for the latest release (over two years ago) state, the transparency feature has been removed (although the commands are still available in the menu).
