Will there be a new release?

When Apple "borrowed" from the LiteSwitch interface they had every legal right to do so. However, if they kill a product in this manner, they should at minimum incorporate the full functionality of that product.

I too miss LiteSwitch. I fear that too many people are willing to settle for Apple's offering. It's akin to the argument for Windows. It's good enough, however, it's very frustrating for someone who is use to the elegance of the Mac OS. Similarly, Apple's switcher is extraordinarily frustrating for anyone use to the elegance of LiteSwitch.

While Apple makes a superior OS, it does not make superior utilities. What makes MacOS special are the myriad independently developed utilities and applications. Doing a half-ass job of copying the general functionality of a utility or application benefits no one and subtracts from the user experience.

If Proteron has ceased developing LiteSwitch (and MaxMenus), it will be a major loss to the OSX platform.
