Dear all, Following the thread on layers: (1. thanks to all) 2. I use ConTeXt for many things, but quantitatively mostly for slides. Powerpoint is rude in its graphic abiltities but it has two features ConTeXt has not. First, you can draw on the screen. Second, you can import and stack images as you prefer. I'm not interested in the first feature, as I use a specific sw for drawing, and then import the result. But I am (sometimes) interested in the second one (let's call it "compositing"). In ConTeXt one can evidently use layers to exactly place and stack everything as needed (images, text). But, especially while preparing slides (a book worth the efforts indeed), it can be tedious to wrote all the code stuff. So, I created a minimal app in python using tkinter which allows to manipulate visually areas ("boxes" in the app terms) which can the be filled with images. The app has a second window which continuously updates with conTeXt code generated by the gui. The idea is that the user prepares a visual layer, then switches to code window, copy the generated code and paste it in the .tex file. Finally code is definitively modified it in the source, as usual. It's very simple, I've tested and it seems to work. But it can be buggy. I don't know if it can of any interest to anyone in the communities. In any case, comments related to whatsoever aspect are welcome. Actually, I've not documented it but it should be obvious. GUI should be completely portable.
