I cannot speak directly to this app 'cause I haven't tried it, but Vicott over at
Mobile-SG has recently been working on a similar app and workarounds for the loss of edits between resets.
IIUC, he found that the editor will 'learn' between resets (newly edited words will not be lost), but the ability to edit the dictionary is lost after you edit it once. His current version claims to get around that problem by fooling the PPC into thinking that after each reset its dictionary is 'factory fresh.'
The latest version, I believe, also allows the use of blanks and symbols into the dictionary file - so you can set up a password, an email address or a short phrase even into the word suggestion list.
You can check out the program
here. The word completion editor also comes as part of a bundle called (imaginatively enough)
DictMgr with other dictionary related programs: a word-correction editor, a spell-checker editor, a T9 editor and a dictionary of common acronyms.
The bundle is really the better deal as you get *even more* for free as oppossed to just one thing for nothing. 8)
This might also be of interest to those who like to tweak on the cheap:
Pocket UI Tweaker is, as the name suggests, a collection of utilites for changing a number of custom settings on your machine. I personally appreciate the
PT Explorer because it lets me keep my tsk files on storage and out of main memory.
/really feel foolish having spent $$ on a dictionary editor a few months ago
