1. They ought to provide a word list in the package--it seems silly to have to download a word list to use the trial version.
2. The first word list I downloaded didn't work; Lingo gave an error message (unknown2.txt).
3. The documentation doesn't say what color indicates wrong letter, etc.
4. The documentation includes a link to online screen shots (that will supposedly indicate the color code)...but the link gives a 404 error.
5. There are, however, tool tips that reveal the color code; they were just a little slow in appearing.
6. Typing in a word guess is okay, but it would be nice to be able to put letters directly in the grid. That would make visualizing guesses easier.
