New to Lectora, will it work for my project?

Can I have a series of buttons in a menu that are not clickable unless the previous Chapter test has been completed?
>> Lectora has both a Menu and Buttons. You cannot have non-clickable parts of a menu but you can set up a series of buttons and have them not-clickable until the previous chapter is done. You cover each button with transparent button or .gif. Then at you have an action at the point when the chapter is complete that sets a variable to indicate/remember that the chapter is done. Wherever you show the buttons, you have page level actions that hide the transparent buttons or gifs based on the chapter being complete.

Does Lectora store cookies, so that if a user is viewing the project I have made and closes the window, they can come back and not have to start all over?
>> Yes you can go this. If you are loading your courses into an LMS, then this is almost automatic. If no LMS, then you have to code this yourself. For complete instructions see Bookmark for Resuming a Course or you can search the forum as I think someone has explained it but as I remember there were problems with that explanation. Not sure.

This particular project has a large amount of content and many tests that lead up to a final test.
>> Long courses are much less successful than short ones.

Is it possible to print the test results from all tests, or save them to a PDF?
>> You can do one test at a time but not all together. I think you can set up a text box on the Custom Results page and put the learner's name in it. Not sure.

 Be glad to work with you to solve these problems if need be.
