assist
Assist is a clone of the Newton’s Assist feature. I used it so regularly that, when I downgraded to a PocketPC, I kept trying to press the “Assist” that did not exist! The source code is posted online at SourceForge. I wrote it in VB6 and Pocket VB for Windows Mobile Devices. There is also a linux version in the CVS. I am currently working on a MacOS version to upload. The MacOS version will work with Quicksilver, and be available as a service. Below is a screenshot of the Pocket PC version. Anyone that wants to make enhancements to the older projects is more than welcome! Please contact me with any questions.
