How to shift buffers?

[Trikes]

For now only a quick update on the order of modules in the XML file as exported by the editor:

• it is not necessary to edit the order manually in the XML file as I did before to ensure the correct buffer build up (my last screenshot above)
  
• it appears that the editor defines the order of the modules at export by their horizontal position "posx" like in
  

  <subrange editor:uuid="2460" editor:posx="350" editor:posy="920">

• in the past weeks, I think, I read in some resource something about the horizontal order but have not found this source again (I believe, it was something like horizontal order is used and vertical order is not; remembered this only again vaguely yesterday)
  
• at my attempt before I manually adjusted the "posx" and "posy" values in XML to have a nice looking view on the experiment in the editor (in the next editor version there could be some "snap to grid" function to avoid that the positions have decimal numbers in which the significant difference which decides on the execution order happens at the 8th position after the decimal point, which is kind of hard to see in an XML file of a thousand lines), this way (XML edit) the two important modules (buffer element source and loss terms, last screenshot) had the same "posx" and their vertical order had most probably being ignored at export, allowing me to define it manually in XML (just in terms of line numbers, simply by copying a module ahead of the other in the file), this reordering in XML was then in contradiction to the "posy" values of the modules as from the editor, but this was without any impact
  
• to avoid the manual XML edit I use now some small posx offset (10) to ensure that one of the modules is being executed ahead of the other to have a correct buffer build (new screenshot)
  
• well, at least this is my current undestanding after some experimental changes in the XML file and importing/experting it to/from the editor several times, still need to test my experiment after introducing this small offset for all such buffer builds
