Uh, Jody, I found out something else to do.
Somehow I managed to freeze the entire program - it seems to have had something to do with resizing. I had to end process on it.
Problem is that before that, I had renamed a checklist, so when I restarted the application, my list was lost.
But I saw my old list - or part of it - in the checklists folder, and I edited checklist.dat to point to the newly-named one.
That went well, except that I lost the last 7 entries I made.
With that in mind, I think that sChecklist ought to save it's list after an edit is made in the list. I'm not sure how often it saves, but it doesn't seem to save after an edit is made, or at least when the application loses focus. I don't think there is any need for a "save" feature.
Another thing to add is a way to import a list - perhaps drag-n-drop would be sufficient. It could take the filename (without extension) as the automated name for the checklist.
Finally, is there any way to have or not have the lines in the checklists list? I know there is the toggle button for the entries (details mode, etc.), but not for the checklists list.
