Hi,
Just wondering how I can put canvases in the "background" if I wish to add them to my patch later. Or do I have to put down the canvases first before I construct elements I want them to be visible over?

The only current way to put objects (including canvases) behind other objects is inelegant and annoying. The process is:

1. select all objects that you want to put objects behind
2. cut
3. put new objects that you want to be behind the objects you cutted
4. paste
5. now you can move the new objects to the correct positions, adjust properties, etc (they will stay behind)

There is a major problem with this method: you will lose all stored information in the objects you cut. This includes number boxes resetting to zero, [float X] objects resetting to X, [bonk~] losing any information you have trained it with, etc etc.

Hopefully Pd will be able to handle this more gracefully in a new version, even more hopefully 0.40 and not 0.67 (due for release in 2033...).
