PocketTools - consist of three apps I wrote a while back. "Replacer" is a find and replace tool primarily for text in the Notepad.  I wrote it as an aid for editing sources on the Newton under Steve Weyer's NewtDev programming environment, but it is also useful for finding elusive text in long Notepad entries.  Replacer is a fairly large app that uses an interesting, if not kosher, programming technique to facilitate compilation in limited heaps. "noButts" is based on a similar app by Konrad Hinsen that creates a floating toolbar.  For my use, Konrad's toolbar is the best of its kind I've seen.

"Ruler" is a layout tool I've included as a programming example.
