It would be great if the order of these 3 elements would be natural, even if you add a lower number later on it should be shown in the correct order as it was in DTM.
As an example I had the following eVars
Then I added eVar5 so the order when I open the Global Vars of the extension configuration or in a rule in the Set Variable element the next time should be the following and nto eVar5 at the end.
