First, let me tell you webissues is a very nice tool : simple and well built!
I have two suggestions/requests:
first, an issue can not be moved to another folder and it's a shame because I would have expected it possible.
second, the text attribute allows only for a one line fill in box. A standard attribute is "description" and it requires a multi-lines box to be easely used.
That's it ! And I like the portable version! It's a real advantage of the tool.
