All files are included in the zip file in the link above, pdf booklets and all the source code.

These booklets cover the four B4X platforms.
Some don't cover B4R because the subject is not relevant for B4R like Visual Designer.

Just to show I'm paying attention, I have to say I've always been impressed with Klaus' documentation.
There are two points I should highlight:
1. It would be good if many examples were brought up to date or an example of how it would be written in B4X/pages. This, of course, is a rediculous expectation. It is just a dream.🤔

2. The docs would work a lot better if I remembered to refer to them. This would save me a lot of time. 😥

OK, but what kind of information would you like to be added there ?
Generic terms & concepts (file handling, saving files etc.) and cross references - even better a list for beginners like me eg. saving a file see file.write etc.

Concepts. By that I mean e.g. context menu or various type of dialogs like B4Xdialog, Preferences Dialog etc. True you find lots of mentions and some code snippets in the forum, but neophytes like me would typically first search through your booklets to find step-by-step instructions or complete examples.

To me, this looks more like a wish for a new booklet rather than with metadata.
