Hey David.
uh... David here.
I like this software a lot. However, can you make a setting that, when enabled, doesn't use Javascript in the created catalog?
Here, let me show you what I'm seeing:

The ^first image^ is Advanced Mode ------------- The ^second image^ is Basic Mode.
Now, obviously Advanced Mode is prettier and uses fewer pages (page numbers in top right corner); However, the "Downloads, Links and other catalogs" links do not work in Advanced Mode, not even if I turn Javascript on. This is a result of the fact that the K2 Browser doesn't play well with popups.
Also, (if this is easier to accomplish than the former,) for the sake of making Basic Mode a bit better, can you make it so that when the "Do not generate external/cross-reference links" checkboxes are checked, that the menu options for them don't appear either? As you can see in the image on the right, I had external links disabled, and though it didn't create external links it still shows the "external links >" option. Maybe you can set it so if you have either of those those checked, it merely comments out the appropriate menu option so you can't see it either.
