Hi Kim; thank you for your very helpful answer. This was exactly the information I needed.
I have some C-coding experience and limited X11-knowledge (once I patched hsetroot for some extended options for my own use), but in principle I think, I could get into it. I played around with the e16-code one or two years ago and found the parts that you mentioned, but it took me some time and I could not estimate, if it was worth to spend a lot more time, because I could not estimate if I would in the end run into some problems or dependencies, which would require to just change and rewrite everything. That is why I am very happy to get an estimation from someone who has a good overview of the concepts and dependencies of e16, that this should be possible, and also to get some ideas, where and how to start. great ;) I also will not go into it during the next beautiful days in the summertime, but since this is burning for years now, I hope to find some winternights long and cold enough to try.
