ShakeQ is a simple render-queue application for Shake.
It lets you queue your renders, shows an estimated time of completion and has a nice option to avoid proxy renders.
It is not a replacement for Qmaster, it does not do network rendering.
On a one man station however, it just seems a lot easier to use.
It was developed for in-house use, and we've used it now for three years and still are.

By the way, ShakeQ is donationware, so if you like it and use it, please donate the amount you think it is worth on the website above.
